Frame Steel thickness

Hi folks, curious about a couple things;
I am ordering my steel today and getting some pre-cut for my welder for some needed back and front replacement of the frame. Its a 1959 Tradewind. I am away from my trailer and unable to measure its thickness, but I do have the lengths.

1- Curious about the thickness of the steel:
Is the 2x4 tubing and C-channel 1/4 thick or 1/8th thick on 1959 Tradewinds?

and......

2- Is it over-kill to replace the original rotted 2x4 C-channel steel with 2x4 tubing, thus beefing it up?

Cheers, and many thanks for helping.

-Muskie

Frame Steel thickness

I can't speak for sure about your trailer , but on my 72 it is all 1/8".

Tube is stronger and better IMO, but its use will likely force a few changes, access, blind corners, etc.

(Tube really doesn't flex, this can be good and this can be bad depending on its use and placement)

But if I was starting with a blank slate on a frame, I would be looking really hard at using tube over channel .

My 66 Trade Wind is 1/8 thick but 5" by 1 1/2 "C" channel, not the 4" older design. I don't know when Airstream changed to 5" frame rails. Some folks box in their "C" channel frame rails in high load areas, like after the axles. The stringers do fit inside the frame rails and are welded top and bottom giving the C channel more strength.


At least you don't have the very old "pipe" frame design!
