It's all about sharing our exp and saving someone some time, energy and money. I love my Burb. The only downside is that it currently costs $130 to fill it.

Glad you've found some of the info useful.

If you were in California, that $130.00, would only fill a small gas tank.

I recently sold our '75 23' Safari and bought an '01 25' Excella, and the dealer sold me the Reese Dual Cam hitch setup with the trailer. The bars that I have are the 800 pound bars, which correspond to the actual advertised tongue weight of the trailer. My tow vehicle is an '07 GMC 1/2 ton, extended cab pickup equipped with the towing package which includes the HD suspension. So, what I am understanding in this thread is, I would be better off, both ride quality and handling, with the 600 pound bars? Is this correct?

You are correct.

Unfortunately, Reese TOTALLY ignores the tow vehicle from it's chart.

You certainly would not use the same bars on an Chevy car, as you would on a Peterbilt.

Change the bars. You will notice a softer ride and better sway control.

Again, the Airstream trailer loves a soft ride. Anything that's done to transfer road shock to the trailer, will ultimately cause damage to the trailer, based on my 42 plus years experience with Airstream trailers.

Stiff tow vehicle springs, air lifts or air bags improperly inflated, Monroe load levelers, Excessive rated torsion bars, and lack of proper running gear balance, all contribute to damaging the trailer.

Most shops don't care, if an owner abuses his Airstream.

Why?

They get to put it back together again, at the owners expense, since insurance companies will not pay for "long term damages."

I am anxious to see how the head of Reese responds when you call him today. Hopefully we can get a final answer and solution. Please let us know what they say.
Thanks

Tomorrow is a busy day for me, so I think I will call the head of Reese Friday, and have a discussion with him, about the stupidity of that chart and what their customer service staff is told to say.

600 lb spring bars arrived...

I received a box from etrailer yesterday; this was supposed to contain the two 600 lb spring bars I ordered; supposed to being the opeative phrase. Only one spring bar was in the box. I suspect the second one escaped through one the two rather large holes in the box and is somewhere between OR and MO. Why they put them in such a large box with no packing materials inside the box to contain movement is beyond me.

etrailer responded to my email this morning telling me that they had no more of these in stock. Given that my email to them had steam escaping from the envelope I am sure they knew that this news would not be well received; it was not.

They told me Reese would be drop shipping another bar from their CA operation and that I would have it Thursday.

So, with a little luck I will be using these next week when we weigh anchor for our trip east and then south for the winter.

I will get pictures and weights, etc., on our way out; we will be stopping at two different public scales as we head east. Then it will just be a question of getting a good internet connection so I can post the updated picture and weight info to this thread.

Jim, I and I'm sure many others will be eagerly awaiting your evaluation of the hitch's performance with the lighter bars.

etrailer strikes again.

I received yet another email this morning telling me that the bar would not be shipping from CA but from Michigan; scheduled to arrive 12 August.

One thing for sure - customer service is NOT etrailers' strong suit.

Stay tuned for further adventures....

Jim

Spring bar arrived...

Hallelujah!!!

Our second spring bar arrived today.

The plan is to hook up to the trailer tomorrow am and head for the scales.

If we are able to get to the scales I will post something tomorrow in the way of photos and weights.

Jim

PS: Did I mention that etrailer contacted me early this week asking that I send them the box that the original bars were shipped in? I couldn't believe it; more than a week after it arrived. To bad it had gone into the trash several days after it arrived.

The final test; at last....

The temperature here finally broke and we have been under 100 degrees for the past several days. I took advantage of this and got the the 600 pound trunnion (spring) bars installed. The first thing I discovered is that the bars are significantly shorter than the other bars I had been using. This caused me to change the adjustments on the sway control units so they "fit" the new bars; by more than an inch.

We then headed for the scales by way of a cul de sac where I was able to watch the action of the hitch as my wife drove around the circle. Needless to say the hitch was pushed to its extreme operating positions as far as the degree of the turn; we came close to jack knifing things but made it.

My first observation is that had we tried this with the old bars we would NOT have made it. I think tight turns were causing the sway units to bend with the old bars. Not only are the old bars longer, they are wider as well at the tips where they rest atop the sway control units. With these narrower bars there was more room for them to move laterally as well as length wise as we went around. The narrow bars allowed for more freedom at extreme angles when the bars tend to twist when extended to the end of the bar over the sway control. Because they are narrower they had more room in the sway control as the angle become more acute.

From here we headed to the scales. Sames exact weights as posted in the first message of this tread.

The ONLY difference with this set up is that the top of the hitch on the trailer is now 19" (19.75 previously) off the ground and I have been able to take off one more link on the pull up chains for the spring bars.

The BIG difference with these bars is that there is absolutely no way I can take off any more links on the chains. The pull up bracket is rotated so it is full down when the chains are attached. It is physically impossible for me to physically pull the bars up further in order to reduce the number of links and thereby increase the tension on the bars. Please note that this was done with the trailer tongue jack raised to its absolute highest position in order to make the "pull up" process as easy as possible.

As for the ride. I notice that it is not as "stiff" as when we used the other bars. I do not know how to quantify this; it is very subjective and based totally on feel. I do notice that the rebound action of the shocks on the rear of the truck seems to have more action now than previously when they tended to not react much to surface irregularities. I hope this makes sense.

Any rate, I think my problems are solved.

Here are the photos from the scale.

Thanks for your post.

Now you have a nice bend in the bars for better control.

Now you have some bounce, which means a softer ride.

Now you state that the ride is more comfortable.

Now, I can say, I told you, I told you and I told you.

I just wish others would heed the warnings and would do what you have done.

Question??

Can we now say that your "much more" of a happy camper?

I think you also are a good witness to the fact that the chart that Reese has published, is full of prunes, along with the music they preach as to what is correct, likewise, is full of prunes too.

The main thing is that you now can see and feel the difference as I told you would happen.

Perhaps with some posts, you can cultivate others to listen as well.

Thanks again.

Andy

Wow...

Wow, that is some serious flex. I have the exact same hitch with a Safari 30/ 3/4 ton Suburban. While my trailer is very level I have a ever so slight lower in the rear suburban. I cannont really complain on the ride, it does however have some serious rebound that is hard to tell if it is caused by the hitch setup or the GM Autoride feature.

When I get my rig back from JC next week I will post some pics of my hitch geometry to see what others think.

Andy I think it is I who owe you the thanks.

What I did not mention in my post is that I had installed a new street side sway control unit on the trailer before we went on a 350 mile (round trip) expedition; this is when I took the pictures in the first post of this thread.

When I started to adjust the street sway control to install the new spring bars I discovered that the threaded rod had been bent during our trip. The bend was just enough to prevent the nut from turning by hand after it had been loosened from the lock nut.

This is the fourth sway control rod that I have bent with the heavy duty trunnion bars. I installed the last one from the last pair I ordered and we went to the cul de sac so I could watch the hitch in action. I am convinced that the heavy duty spring bars were the problem after watching the hitch through this tight turning radius.

Any rate, I do want you to know that I really appreciate your responding to this thread and offering your wisdom; it sure has made the resolution of my problem much easier.

Thanks again,

Jim - who is off to his home made ice cream and fresh peaches for desert....

WHAT!!!

No whipped cream.

Darn.

And thank you, for the thanks.

Hopefully, through your efforts, maybe others will listen and join the new found ranks of a "real happy camper."

It's really very simple.

Get off the heavy duty everything wagons.

One of your peers, listened, and is now is enjoying worry free proper handling.

The real problem is that it's so easy to fix, that most people just seemingly can't get themselves to believe it.

Who else wants to join the band wagon?

Regards.
