I have Timbrens on my Suburban.
On my Excursion I had the Roadmaster Active Suspension installed. The RAS helps softly stiffen the rear suspension. What the RAS is , is a long spring hooked up to the rear leaf springs. I noticed an improvement in the ride as soon as I had it installed.
I looked at airbags before I found out about the RAS and preferred the RAS since once it is installed you do not have to do anything to use it.

Rob,

I hope the dealer works something out for you, they should have given you a higher rated WDH in the first place. Tell them the 800 pounders would be great if you towed an empty TT!

The suggestions that forum members posted on rear suspension options are worth considering as well, I have some friends that have done the same and are pleased with the TV ride improvement (they tend to load heavy in the TV; generator, wood, etc.).

Bob

Great investment if you tow alot. I dont usually have to use them only when I put my atv in the bed of pickup when hooked to trailer (one ton with overloads). Air bags came with it when I bought the truck. Came with camper tie down system. But would have added air bags if it didn't already have them. Happy camping and welcome.

Well Gentlemen,

I have gone to the dealer and I talked to their service manager. We went over all the options and talked about my issues with the hitch and WDS. We got out the specs on the trailer and he assures me that my hitch is fine for my truck and that those Firestone Air Bags would be my best option.

So, I got a price from him $450 + 2 hrs labour at $109 per hour. Then I would get %15 off the total.

I got a second price from my father-in-laws Dodge Dealership (he is the service manager in Penticton, BC) and he can get the same system for about $50 less but then I have to drive further to get them installed.

I better move as I am in Oliver BC doing a Triathlon this weekend and then the following weekend in the Shuswup camping for May Long.

I will let you all know how it turns out.

Thanks again,

Rob

As like many others (who tow trailers in the "real world"), I would:

1 - Weigh the "loaded" trailer's tongue. This can be done at the formal road scales or by using a simple bathroom scale. For bathroom scale method, surf contents of: http://www.etrailer.com/faq-trailertowtips.aspx

2 - If trailer's REAL tonque weight is 900 lbs (or more), I would get WDS system with 1,200 lbs. And, sell those under sized 800 lbs WDS bars.

Remember that WDS (with 'properly sized' bars) is used for trailer's tonque weight. Air Bags, RAS, Timbrens are used on a Vehicle with NO trailer connected. Yes. Both will work together. However.... Do remember that using "under sized" WDS bars and using Air Bags for correction is not only geometrically wrong but its very dangerious. re: Under sized bars allows too much trailer's tonque weight on TV's rear axle. Thus, less steering traction (on the TV's front tires) and over stressing the TV's rear axle (and its shocks).

If "loaded vehicle" is level and has firm factory suspension (before connecting to a Trailer), I would get properly sized WDS bars. I'd only install Air Bags, Timbrens, RAS on the TV if the "loaded" vehicle (with NO trailer connected) has sag or has factory mush suspension - like my mini-van. If wondering, I installed Timbrens in my mini-van and love them. Especically when my vehicle is "loaded up" (with NO trailer connected) with people and cargo.

I was looking at a pair of these not too long ago. I ended up with just going with a set of 4 HD Bilstein shocks. My truck kind of bobs up and down when towing, my only complaint. So I'm just stiffening up the ride a bit. But if that still doesn't do the trick I think I may try the airbags in my link. Very cheap and looks like a very easy DIY install.

I love my Timbrens. They don't require any maintenance or air or develop air line leaks. And they are guaranteed for lifetime. Although I don't know if that means their lifetime or mine.

Rob,

First, good luck on the Triathlon! :nike:

I guess I'm not surprised on your RV dealer's response, very few RV dealerships truly understand how to correctly size/adjust a WDH to a specific TV/TT combination for real world "loaded" towing conditions.

I'm reaching here, but lets assume your dealership is using the WDH industry standard of 10% to 15% of loaded TT weight for the loaded tongue weight for his line of thinking. To support his opinion that an 800lb WDH is the correct match for your TT, he would be using the low end of this standard range. What he may be doing is focusing only on the TT's weight specifications, and not considering it's 30'-6" overall length. This is where the 10% to 15% range comes into play....., longer the TT the higher you want to move within the recommended loaded tongue weight range, thus allowing for enhanced handling characteristics with the longer TT while you are rolling down the highway at 65mph.

Many seasoned "tower's" recommend the 13% to 15% on the longer TT's, but in most cases with the heavier/longer TT's IMO 15% minimum is more desirable.

I hope he wasn't basing the WDH 800lb sizing on the TT's dry hitch weight of 750lbs (this also wouldn't be a first).

Do check back in and let us know how you finished in the Triathlon, as well as your towing experience.

Bob

I'm with you Rustic.

I've yet to hear the dealer state that one needs to "load up" their TT as if going on a camping trip and measure the TT's tonque weight. This can be done in the driveway using a bathroom scale. The "real world" weight number will clearly state the size of bars that are needed on the WDS system. It's so simple... Yet, I didn't see mention of this rule.

TV opine

This is a bigger pic of my TV and TT I use for my profile. This is brand new and right before we took it off the lot.

Members take a look and give me some insight on the set up. This thread has me wondering if I am too low or not.

I am running 1,000# bars.
