WDH vs. Shocks

I bought a 2008 Jayco X23B last August, and I drive a 2008 Dodge Ram 1500. When I bought the camper the salesman said a WDH really isn't needed unless the back end of the towing truck drops more than 4 inches. My truck dropped about 3, so he didn't suggest I get a WDH. It seems to me that if anybody is going to tell somebody that they need something, it would be a salesman so they could make an additional sale.

So, what is the best way to determine if one is needed? It seems that some people seem that it's a forgone conclusion that if you have a camper, that you need a WDH. Which seems like it's simply assuming that one is needed without legit reasons why.

Also, it seems like heavy duty shocks may keep the back end of the tow vehicle up at the proper height anyway. So wouldn't that take care of the need for WDH?

I'm going to get a sway bar, but if I'm buying the sway bar, and I actually need a WDH than it makes more sense to buy as a package deal.

Please let me know your thoughts and what makes sense.

The amount of TV rear end squat isn't the important factor, what you should be looking at is if any weight was removed from the front suspension of the TV (or front rise) when the TT tongue was placed on the hitch ball.

My BIL had a 2006 23B and his loaded tongue weight was 650lbs, he used a WDH rated at 800lbs..... worked great.

If you really want to know what's going on with your particular TV/TT combination (weights, confirm WDH size/adjustment, etc.), I would visit a CAT scale. The following JOF link will walk you through the process:

Hope this helps.

Actually shocks will not do anything to raise the rear. They simply dampen the bouncing. You would need air bags, add-a-leafs or Timbrens to raise the rear when loaded.

I'm not saying it will raise the rear, but wouldn't better shocks reduce or eliminate drop in the rear?

I would also look at the capacity of your hitch in "weight carrying" mode, with no WDH. I would ensure you aren't exceeding that rating.

With NO trailer connected, load up the rear of your vehicle and drive around. Does the rear of your vehicle feel like mush? re: Too soft. If yes, get HD shocks installed in the rear of your Vehicle. Remember that shocks don't lift a vehicle. They only reduce the speed of up/down movement (when going over deep bumps). Many folks sometimes call it a "bounce test". If bounced more than 2 times, then replace shocks. And if replacing, replace with better then factory grade shocks.

With loaded vehicle (as if going on a camping trip) WITH trailer connected, drive around. Does the rear suspension of your tow vehicle feel like mush? re: "2 bounce test" thing. If yes, then install HD shocks. Do keep in mind that if upgrading with HD shocks (like HD Bilstein @ http://cart.bilsteinus.com/ ), the "loaded down" feeling will feel much firmer. But, it might feel "too firm" during empty load. Thus, don't over buy HD shocks for your vehicle. Sometimes, too HD rating replacement isn't good. Especially if daily ride - that runs empty most of the time.

With NO trailer connected with vehicle's rear loaded (as if going on a camping trip) and vehicle's rear sags down too much, simply install Timbren SES units. They are like air bags without compressed air inside them. Thus, no worry about air leaks. Simply install and leave them. Or if you prefer air bags, then install air bags (which are adjustable) instead. Timbren and/or Air bags are made to reduce vehicle's rear sag when NO trailer is connected. Timbren SES units or Air bags are made for Vehicle.

With trailer connected and rear of vehicle goes down too much, I would install a WDH - with properly sized bars. A WDH System does more then reduce vehicle's rear sag. It also transfer some of the trailer's tongue weight to the Tow Vehicle's front wheels. Not much weight transfer but on slippery roads, every little bit counts. WDH System is make for Trailer's tongue weight.

If wondering, I installed Timbren SES units under my previous vehicle and my current vehicle. When loaded down and NO trailer connected, they work great. Especially since both of my vehicles have factory "soft suspensions". And, they also work great when trailer without WDH system (like my utility and boat trailer) are connected as well. But for my heavy tongue weight RV/TT, I always use a WDH System (with properly sized bars). Both do work together - if adjusted properly.

Long mumblings short... You may need to install HD shocks (to eliminate compression speed), you may need to install Timbren SES or Air bags (for Vehicle rear support) and you may also need to install WDH System (to support RV/TT's heavy tongue weight). I installed all 3 upgrades in my previous Vehicle and it was money well spent...

Note: For your Dodge 150 (with soft factory suspension) and 23ft TT, I would buy/install a WDH system (with properly sized bars). I might even install Timbren SES units if vehicle had too much sag with NO trailer connected. And, I'd do the "2 bounce test" to determine if new / replacement shocks are needed.

Hope this helps...

A better (Premium, HD, etc.) shock will have very little, if any, influence on controlling rear TV squat when placed under load, especially the effect of your HTT tongue weight.

A WDH when adjusted properly will however minimize rear TV squat. The WDH's main design function is to "return" the weight that was removed from the TV's front suspension do to the effect of the HTT tongue weight being placed over the TV's hitch ball. The HTT tongue weight placed on the hitch ball remains fairly constant.., but the WDH will remove some of the added weight off the TV's rear axle and transfer (return) the proper weight back to the TV's front suspension........., thus the removal of weight off the TV's rear axle in concert with the WDH's supporting charactoristics reduces the amount of rear TV squat. The WDH will also transfer some weight (from TV rear axle) to the HTT's axles.

Your thought of getting a sway bar and WDH as a package deal has merit, based on your described TV conditions. As Spike99 mentioned, if you find that your existing shocks are worn, a new set will enhance your towing experince.

A WDH will take weight off the rear tires, add weight to the steering wheels and the trailer wheels. It will also help reduce sway and push when you meet the big trucks.

The shocks don't hold your truck up, the springs do. The shocks just controll the wheels so they don't bounce when you hit bumps.

This is the correct answer. When new whether OEM or after market your hitch had two weight ratings,(not to exceed) on a sticker or possibly stamped into the hitch itself.
Most OEM hitches are rated at about six hundred pounds. WDH rating is much higher.
I towed my 23b on the ball about ten miles to my fathers place, never again. The WDH creates a much stiffer unit and except in extreme conditions the bounce is gone and what is left is damped by the whole length of the truck.
