Hi all,
Just after peoples opinions or experiences with campertrailers with a draw bar that extends right to the rear of the trailer, with the spring hangers welded to it and the cross sections welded into it. Pretty much one big peice. Am lookin at trailers and have seen a few with this and wondered if it is as good as it is made out to be, and if maybe it has some drawbacks. Seen some where the draw bar goes back to the front of the spring hangers too.
Any feedback appreciated
Cheers
Brettj

That sounds like a pretty strong and rigid trailer chassis. Would be rather heavy though. Unless you're going to be lugging lots of weight or some serious off road work, is it necessary?

how much heavier would it be? You would think not a great deal as you would be only replacing 2 peices of 50x50SHS with a 100x50 RHS. Istead of a box attached to a draw bar so to speak, it is all one unit. To my way of thinking it would seem stronger.

Most true off road camper tarilers have a full chassis.

Do you mean the draw bar has been cut on 3 sides and welded right at the front of the trailer .
Me I would rather have one continous length of RHS from the hitch to the spring hanger with no welds though the walls of the RHS. Just my opion.

no Scoof,
The draw bar continues all the way to very back of the trailer, one peice. The cross supports for trailer floor, usually 50x50 are welded into the draw bar/chassis. Hence it is not your typical box trailer. Effectively the draw bar is also the chassis. Has to be better doesnt it? No welds.

Hi brett,
I just think it would be very time consuming for the fabricator to build a trailer like that. Instead of all your cuts being square they would all be on opposite angles.
He has used more Draw bar material and save a small amount of small RHS.
Sounds like a lot of work to me for little gain.
Assuming the draw bar is still in the shape of a A or (triangle type shape), and the top of the trailer floor is also the top of Draw bar and supports or am I on a different page to you?
Cheers Scoof . :-)

I think you are thinkin different to me mate, the draw is as per normal but instead of stopping at the start of the trailer, the two peices are bent and straighten up to continue to rear. The spring hangers are welded off this, and the 50x50 that supports the trailer checkerplate floor are welded into the sides of the 100x50 RHS

Now that is nothing like I imagined, this similar to my boat trailer. No angle cuts .
That is a good looking set up.Its been bent at the front were I thought it would of been cut on three sides.Very simple.
Cheers Scoof.

We have a box trailer with exactly that design.
It is old, like very old. It was involved in an accident prior to us obtaining it and it wrote off a BMW. It is only a standard 7x4, not offroad but I have had 1.25 ton in it and it never worried it one bit. We have found it to be strong. The drawbar hasn't bent 1mm like you see some box trailers.
I also have an off road camper where the draw bar is welded to the chassis just in front of the spring hangar. It is also strong however is larger cross section in steel.
Both good trailers.
Scott
