I have the anti-jack-lean modification installed now and it works great.

The kit includes two small pieces of U channel that fit between each U bolt and the A frame, and two rectangular pieces of flat steel stock that fit between the 7/16" clamping bolts and the A frame. The jacks are noticeably more secure and don't move when pushed from the top by hand.

Just wanted to chime in here and say we now have about eight thousand miles towing with the PP and couldn't be happier.

Great info - how would the PP3 install go on a 34' limited with the cowling and horizontal tanks in place? Has anyone done this?

hi 'wave...

welcome to the land of quality towing gizmos.

quickly searching does not yield any USEFUL pix of the tank cover IN PLACE.

http://www.airforums.com/forums/f287...ada-54494.html

take a few pix and post them. (along the same lines as bill in post #235)

((if u need help posting pix, there are CLEAR how2s threads on this...))

-entire A frame area (ball back to skin)
-underside of the same (jack back to shell)
-closer up of the A frame top side...

and IF u really want solid responses, PLACE a YARD STICK along one of the A frame rails...

cheers

Going from memory, I think there should be enough room on the sides for the jacks. I don't remember the tank cover extending all the way to the tongue jack. As 2Air said, pics would help a lot!

I am a self-proclaimed newbie and my maiden voyage from WI to AL of 740 miles and one short trip this past weekend represents the total extent of my AS towing experience. I would like to get some feedback on what causes front-to-rear jerking or bouncing when braking or hitting road bumps. In general, is it too much or too little tension on WD jacks? Upon Sean's suggestion to raise the jack to 4-5" on day of delivery and installation (a nightmare btw - but another story - couldn't have made it without Sean's weekend on-call support), I still have not found the "sweet spot" if one exists. Any insight would be greatly appreciated.

Thanks,
Chris

hi chris

post up a picture or 2 of your rig, this always helps with cyberarmchairbackseatdriving.

and before we all chime in with theory and solutions to your issues...

>> clarify this "front to rear jerking or bouncing" issue...

does this mean when applying the brakes the yukon is tugged back or pushed or both?

>> did someone SETUP the trailer brake controller and dial it in properly?

http://www.airforums.com/forums/f464...ump-58101.html

>> how much air pressure in the yukon tires (do you add air for towing) ? ...

tension on the w/d bars-jacks is used to help REload the yukon front axle so that steering control is normal.

>> have u measured the 'stance' or weighed the rig and each axle on the yukon ?

this may seem like more trouble than you want, especially as a noob' but still important...

here is some background and examples from others...

_________

on SOME sections of roadway and with some tv/trailer combos

there may be occasions when the rig seems to porpoise or rock/roll forward.

>> is THAT what's meant by 'front to rear jerking or bouncing' ??

this is not something that can be entirely 'adjusted' away,

since it's related to irregularities in road surface.

IF that happens simply lighten up on the GO pedal

and slow down a bit, till PAST that section of roadway.

IF porpoising is happening ALL of the time...

check air pressures and hitch install and setup and trailer loading.

we all start somewhere,

and finding the sweet spot includes COMFORT and acclimation to driving WHILE towing...

>> so post up some pics, read a bit and 'splain more.

post up a picture or 2 of your rig, this always helps with cyberarmchairbackseatdriving. Regarding the pics, since those were taken and per Sean's suggestion, I have raised the hitchbar by one hole. This has helped level the nose of the AS.

>> clarify this "front to rear jerking or bouncing" issue...

does this mean when applying the brakes the yukon is tugged back or pushed or both? I would describe it as tugging back & forth or porpising (sp??) as you describe below. I do not believe the TV is being pushed. Accelerating out of it helps. I just wasn't sure if the WD set up played a role in such movements.

>> did someone SETUP the trailer brake controller and dial it in properly?
The hitch and the brake controller were both set up by the dealership. Properly - that's questionable. However, the TT brakes are clearly engaging before the TV. As a matter of fact, this weekend I commented that I thought they were "grabbing a bit too hard".

>> how much air pressure in the yukon tires (do you add air for towing) ? ... MAX per tire = 35lbs front and rear.

tension on the w/d bars-jacks is used to help REload the yukon front axle so that steering control is normal. Could I be raising them too high - even though the TV-TT appear level? Could that create such a movement when towing?

>> have u measured the 'stance' or weighed the rig and each axle on the yukon ? No, and I suspected that you'd ask (note, I was counting you to reply! Thanks for doing so!!). I plan to re-read some of these threads and get the weights this weekend.

this may seem like more trouble than you want, especially as a noob' (that's me - though I am happy as a lark ) but still important...


there may be occasions when the rig seems to porpoise or rock/roll forward.

>> is THAT what's meant by 'front to rear jerking or bouncing' ?? As noted above, that seems to be a fitting description.


IF porpoising is happening ALL of the time... Not all of the time - very smooth ride/feel the majority of the time. Primarily noticing this when slowing down.

Again, thanks for the feedback. I appreciate it very much. ...learning.

-Chris

ok, good followup chris...

>> based on the pics i agree the tongue is/WAS a tad low and the yuk' rear a tad low...

so the adjustment sean suggested should have helped those things.

confirmation will happen with the weigh in or wheel well measurements.
___________

>> IF the yuk' has auto leveling or rear bag assist the process for set up is specific and covered in other threads...

((i can point u to them if needed))

>> 35 psi SEEMS too low for towing pressures,

but u will know EXACTLY what psi (or close) AFTER THE WEIGHT readings...

this also is dependent on which tire is on the yuk' (again lots of threads on inflation pressures for towing)
___________

>> porpoising can happen with any hitch,

and some folks think/report adjusting w/d bars will improve OR worsen it...

so base the adjustment on axle loading.

>> yes a "light front" might contribute to it

but if the steering feels good AND the towing ride is good MOST of the time...

i doubt it's a light front at the source.
___________

IF this is mostly happening when braking, the trailer nose may be diving some...

>> what w/d bar rating did you buy and again LEARN the tongue weight for this exercise.

>> also IF the tv tires are UNDER inflated (relative to towing loads) that may cause some rock/roll when braking too..
__________

u can read about the rockn and rollln here, or search using the P word (not pp)

Got back from our Alaska trip Wednesday, 14,745 miles total, and had about 1000 +,- miles towing with the PP before we left. Absolutely no problems at all, and this is over all types of roads, road conditions, and speeds. Never a beginning of a sway, not even a bobble.

I will never go back to a Reese, or any other brand of standard WD hitch. Best money I ever spent.

saw this orphan post from another pp user...

http://www.airforums.com/forums/f464...ion-68176.html

BY ALL MEANS YES post questions here...

that's what makes a thread like this one USEFUL and rich in content.

also everyone subscribed to this thread will see it eventually,

while a solo post will ROLL off the front page and might be missed by the regular users who can help.

some folks LIKE their questions Unencumbered by long threads, and that's cool too.

(everyone should POP OVER to the linked thread and READ the complete details.

____________

this quote basically sums up the issues reported ...

However, I am noticing that where ever I pull the trailer, against the wind, with the wind, uphill, downhill, 55MPH, 65 MPH, I still get between 10 and 12, not the 14-15 I got in the past. Also, seeing some feathering/cupping on the outer edge of the tires that I have not seen in the past. To top that off, I am getting some "pushing/pulling" to the left when braking....

working backwards on this list of issues...

1-ANY push/pull from the hitch head suggests brake adjustment is needed.

2-it would take a LOT of effort to mount the pp such that the trailer tracks CROOKED...

-the pics LOOK like a normal install but side views aren't ideal for judging "centered" mounting.

-still IF the hitch is crooked, i'd expect to see UNeven wear on the yoke parts and an OBVIOUS Asymmetry at the hitch head.

3-feathering/cupping on the trailer tires (not the truck) right?

-again it would take a LOT of hitch asymmetry to cause this, but tires wear oddly for a LOT of reasons.

-often this doesn't show up till mid/late tire life so i'd wonder when this might have began.

-i'm a fan of ROTATING the trailer tires every 10k at least.

-IF the hitch were causing a tracking issue resulting in tire asymmetry,

-i'd expect to see INNER edge cupping/wear on one side of the stream, and OUTER edge changes on the other side.

4-a change in fuel economy of 30-50% is a lot and i can't imagine how the hitch might result in THAT change...

unless it's DRAGGIN' or anchored to terra firma...

______________

the investigations noted in the original post

suggest you've REALLY checked this over carefully and looked at most of the major issues...

nice goin' !!

-one issue to address ALONG with brake controller adjustment is lubrication...

-don't forget to KEEP the w/d bars WELL lubed at the bushings.

-one side TIGHT or DRY could lead to tracking issuea, tightness in turns and so on...
_______________

so you might add a few more pics (over the TOP) for more ideas and extra opinions...

a LOSS of fuel economy suggests a truck issue imo.

i experience about the same fuel economy change while returning from a long trip

and it was traced to a torn turbo hose and fouled egr valve.
__________

another random thought...??how's the receiver LOOK on the UNDERSIDE of the truck ?
__________

most unusual but hopefully others will ring in with more on this and get your problems solved ...

cheers

Thanks 2Air,
I will be removing the tanks, etc. to take a closer look at the Yoke/assembly, etc., over the next few days. I will get pics to share. I also agree, knowing how the assembly pivots it was hard for me to believe that it could be the hitch, but i thought I would ask those that have used it if they had similar issues. it may be that now that the hitch is "free" to move, any issue that I had with the rest of the drive train is now showing up.

I lube every time back in port...2k miles or so

It is the trailer tires that are feathered...could be an alignment is needed and you may be right about the this issue being there well before the hitch. further inspection will tell and I am ready to take the trailer down to the alignment shops to see what is really the condition of the alignment.

Last note, don't know if others have had this issue but I had a problem with safety chain length on my last camp. During the install, I wanted to keep the safety chains as short as possible as it was my understanding that the shorter, the better. My chains have been just long enough to comfortably hook into the holes at the receiver during a straight on hookup. They ride at a good height while straight. During my last camp, I had to back in at a fairly sharp angle and when I was ready to unhook, the chain opposite the turned truck could not be unhooked. thankfully I was able to pull the pin on the lengthening link that was provided. I will be adding another link and see if I have the problem again.

yep, looking at the install without the tanks will be useful.

IF the under FRAME BRACKET (see post #10) that retains the yoke has slipped sideways,

that would alter hitch alignment, but this should be easy to see and obvious.

((on the older la'orange version it is COMMON for folks to much up the hitch center...

by fiddling with the strut bars tension on 1 side vs the other))

ok, lots a lube, good!

the FIRST set of gyms on my trailer showed outer edge wear but it was only obvious approaching 30,000 miles.

i have had the "tight chain on one side" happen once as well,

there is a couple of extra links on the chain extensions, so i let one out and solved the issue.

look'n forward to your follow up.

cheers

"Pushing/Pulling to the left when braking"

2001excella,
I am curious if what you are noticing with with the "push/pull" is similar to what I asked 2air about a couple posts back. I've copied some of that discussion below:

does this mean when applying the brakes the yukon is tugged back or pushed or both? I would describe it as tugging back & forth or porpising (sp??) as you describe below. I do not believe the TV is being pushed. Accelerating out of it helps. I just wasn't sure if the WD set up played a role in such movements.

Is it a tugging back and forth type movement upon braking?

Thanks
Chris
