are some trailers incompatible with weight distribution hitches

I don't know your pup, but any pup wit a c channel frame/tongue cannot accept a weight distribution hitch. It needs to be boxed or solid. I know someone who folded their tongue skyward on a Rockwood pup a few years ago because he was using weight distribution.

 

I'm surprised your Tundra sags that much. Might think about weighing the trailer and hitch loaded and seeing if you can rearrange how you pack the trailer.

 

My jayco has a C-channel tongue and allows WD systems to be used.

 

Yours is the first C channel tongue that I have ever heard of allowing the use of WDH. .

 

It's also not a bolted on A-frame, as it seems to be one piece with the rest of the trailer. Searching on e-trailers, they also seem to suggest that many c-channel trailers are compatible with WDH, as long as the open parts of the C channel are pointed inwards and facing each other. Jayco may be the exception thouhh to actually allow WDH on C channels, but I'm not 100% sure.

 

From the owner's manual of my 2019 Jayco12UD,

 

Why not ask Forest River? Curious how you determined the hitch weight? If that is what is in the manual, it may be without anything on the huge storage platform up front... If you are carrying a 500lb ATV up there, obviously, your numbers may vary.

PS: Looks like it has a tube frame, so you may be OK for the WDH, but I'd still ask FR.

Some sag is normal. Lots of sag not so much. Adding weight to a truck, pulling or carrying will lower the back of the truck a bit. How much sag are you talking about? If the hitch at the right height? Your tundra shouldent need a weight distribution hitch. But as stated , it depends on loading.

 

Same for me as well. It would be interesting to know what Jayco did to a C channel tongue to strengthen it enough to allow W.D.
Either way, If I were the owner of a pup and unsure if my tongue would allow use of weight distribution, I would want a written guarantee from the manufacturer. As I said before I have seen proof of the damage it can cause. I've never seen a tongue at a 45 degree angle from the frame before I saw this one. It was nuts!

 

Wouldn't happen to have been Pauls and Charlenes would it?

 

Yup

 

Dexter approves their frames made for palomino, very ole thread I've posted before, from 2009.

I believe it's due to being integrated into the trailer frame, not just being bolted on afterwards. I mean, we're not talking a 1000lbs setup here, more like 400.

 

My 2004 Palomino C channel tongue was one piece into the main frame rails and they had it right in the manual.. WDH was not advised ..

I know the jayco DC is talking about was identical in that its tounge was one piece with its main frame rails.

 

In the thread I posted, palomino voided the frame warranty if a WDH was used but luckily that owner got in touch with the trailer frame maker that would warranty the trailer with WDH if WDH rules were followed.

My coachmen stated wdh 'not reccomended' (its use was not prohibited) but at one time coachmen was suggesting the use of the single bar 400 (no longer available).

 

Took a few pictures of mine, if anyone is interested in the A Frame construction method and allowing weight distribution with jayco.
