Jim,

IMO, and based on the conditions of your statement.., a 1,000lb WDH wouldn't be required.

One last question that I can think of and it just came to mind, is a trunnion or round bar better?

From reading online Trunnion seems to be for a stiffer ride with larger weights were as at around the 800lb mark a round bar might seem better?

Sound about right?

I vote for the 800 lb round bar with your set-up.
I think you're right about the round bar having more flex which equals a better ride in that weight category.

If you're concerned about having enough road clearance under the WDH bars, the trunion provides that. Removing the trunion bars from the hitch head has less chance of you getting greasy.

So, really in the end, it comes down to your personal preference in the choice between round and trunion.

Some WDH manufactures offer a wider selection of trunnion rated WDH's then round bar WDH's, but a 800lb round bar WDH and 800lb trunnion bar WDH will produce similar degrees of flex under the same load condition, thus maintaining the required (consistent) weight distribution.

One of the advantages of a trunnion WDH that I like is that the ball mount has twice as much tilt angle adjustment (Reese standard WDH product, I don't know about a Curt) over a round bar WDH ball mount.

Not all TV/TT combinations are created equal.., but some folks have found that a round bar WDH works well with TT couplers welded on top of the A-frame, and a trunnion bar WDH works better with TT couplers welded on the bottom of the A-frame. This line of thinking addresses potential interferences and/or clearance issues that can surface with some TV/TT combinations.

Bob,
Correct me if I'm wrong, but I think if he went with a basic Reese WDH, he could add a few components later to go from a friction bar sway control, to the Strait Line type of sway control. Is this how Reese has set-up their product line?

David,

Your correct, and a good point...., both the standard Reese Round bar WDH and Reese Trunnion bar WDH are compatible for the Reese HP Dual Cam upgrade.

So I finally got around to purchasing a WDH and ended up going with a 800lb set up as I do not plan on driving with much water in the tanks...........anyway I ended up emailing Jayco direct as I could not find a stamp on the A-frame anywhere saying if there was a limit on the capacity of the WDH, here is the response:

Thank you for taking the time to contact Starcraft Customer Service. Your comments and questions are important to us and I would like to help. The weight distribution hitch system is designed to closely match your tongue weight. In this case, bigger would not always be better. Since the GVWR is 6,000 pounds, we can approximate a fully loaded camper will have a tongue weight of 900 pounds. Again, this is fully loaded. So we would recommend any range of distribution hitches from 700-1,000 pounds.

Thank you,

That is an interesting response. Two months ago, with our new larger TT, I asked Jayco for their opinion on WD spring bar size. They declined to give me an answer, and instead referred me to the maker of the hitch, which I did do.

Regarding the A-frame stamp for load rating, it appears only those TT in the lighter weight category get that kind of marking. I guess they figure those are the only ones with any need for worry.

FWIW, Jayco's response may have been the correct answer. When we purchased and installed our Reese Straitline hitch through Orlando RV, I asked the service manager about correct bar size, since I knew less than nothing about WDW hitches. He recommended no more than 800 lb. trunnion bars for my setup (WhiteHawk, 610 lb. empty hitch weight towed by a Ram 3500). Some may wonder about the need for WDW with a one ton truck, but in the Dodge owners' manual in the section covering towing, Dodge clearly recommends a WDW hitch with sway control for any Class III or IV towing application, or if the trailer to be towed exceeds 2/3 of the truck's GVW (I believe that is the correct figure).

In any event, the combination tows/tracks very well to date. I do all I can to keep more weight toward the tongue than the axles. I guess if one goes too stout on the bars, the concern is receiver or frame damage.

I ended up going with the round bars as clearance is not really an issue and I thought based on what I have read and listening to others that it would be a smoother ride. I guess I will find out.
