So...

1. Measure the front fender unhooked
2. Hook up the PP
3. Adjust the bars to return the tv back to its height when unhooked
4. This should be 5"-6" (somewhere in that neighborhood...

Is that it in a nutshell?
Trust me - if I can manage the scales - ANYONE can :-)

But for starters, you have the idea. Odds are very low you're looking at 5" of lift. It might be more like an inch depending on the stiffness of your truck's rear suspension - which is exactly why the scales are really the best way to measure but for sure, start with the fender measurements. Do double check your truck's manual for specific recommendations for your unique setup. One size may not fit all!

Good luck!

Oh - you mean 6" on the jacks - yes - that might be the zone - Pharm's pic is a good guide.

You have got the idea and his pic is a good aid. either the manual or this thread recommended a piece of tape on the supplied long wrench handle so that you can use it to measure the jack height on subsequent hookups, no need to take a tape measure with you. You use the tape height at the wd jack.

just to provide some understanding (and correct me if I am wrong) as you seem to be questioning the concept of moving the weight back up on the front axel...

when you put a load on the back of the truck like that with travel trailer tongue weight - it drops down the rear end, and it tends to lift up the front end.

If you measure the height from the ground to the top of the front wheel well without trailer hitched up...it will be X.....then when hitched up, it may be X+Y...giving you a higher elevation of the wheel well.

AS I UNDERSTAND - one of the issues with this is that your steering and control of the vehicle is more “loose”.....I can verify this in my experience as I once tried 5.5 inches with alot of stuff in my truck for a trip and just thought I would give it a shot and see if it made things a tad less bumpy or harsh...and I quickly pulled over on the next highway exit as it felt downright loose and WEIRD...jacked it up to 6.75 and it felt as I felt it should....(I had a bunch more stuff with me on that particular trip including a 10x10 pop up tent and other stuff usually not going with me...

hope this helps kinda clear up things a tad.

Im off to put some tap on that thing for next time

goto, the concept of the wheel wells is therefore:

1) measure height from ground to wheel well unhitched
2) Hitch up and crank up the WD jacks to X height
3) measure again the wheel well height from ground....
4) adjust WD jack to make the wheel well match #1

That should in theory then get steering back to what it was without the trailer hitched up....

That is the principle anyway as I understand.

So, the height of the weight dist jacks can be done without a cat scale?

Yes - I have done it so far and just kept trying different heights of the WD jacks and went on "feel" - others choose based on the wheel well method described - and others use the cat scales to get the most exact result

Can someone tell me what page the cat scale technique is accurately described? If the opportunity presents itself, I'll give that a go as well

So, at the CAT scales, is the goal there also to restore the tow vehicles front axle weight?

Starting to make some sense now! I think
