1992 Coleman has drooping frame

It says Destiny on one side and Royale on the other so probably not the best frame.

So you have a 1992 Coleman Destiny Royale. In your original post you said -

"We bought the Coleman tent trailer new in 1992 and it served us very well.

The frame started to droop in the first few years and I asked a local welder to fix it."

Since this Destiny series trailer carried a 5 year Coleman warranty on the frame that raises the question as to why you didn't take it back to the selling dealer and have the frame properly repaired under warranty rather than a local welder. :h Since your manufacturer is now out of business the only suggestion I can make is what I've already offered - take it to a qualified welder and see what he can do to resolve this issue for you.

FWIW, I went back through my collection of Coleman brochures and found that Coleman dropped the C-channel frame completely for the 1994 model year so all models produced that year and all following years had a full box frame that carried a lifetime warranty, avoiding exactly the problems you're now having with your 1992 C-channel frame.
