Why not aluminum? I have an aluminum boat trailer. Works very well.
3400# boat. The Covette has an aluminum frame as well as the Cadillac
bodied Vette. Look at a Corvette and see what they use. Airplanes
have aluminum frames. And as long as you design well, the flex should
not be a problem.


Aircraft have aluminum monocoque construction. Any plane with a frame
has steel (or wood) frame.

Aluminum bicycle frames have a very limited lifespan.
The corvette uses a "space frame" which is significantly different in
concept, design, and stress, than a Jeep Ladder frame.

Boat trailers are rarely twisted the way that off-road vehicles routinely
are.
Boat trailers are triangular so by basic design see very little
flexing.

The same thing applies to Corvettes.

After all, when was the last time that you went rock-crawling with your
'Vette? Grin

How about mud-bogging or bouncing around on deeply-rutted roads?

Jeeps are expected to do all of these and more without any ill effects.
(Getting dirty/muddy is, for a Jeep, a good thing!)
