I am restoring a 64 tradewind and I currently have all of the aluminum off of the walls on the inside. I was toying with the idea of trying to find something different to use on the walls instead of the aluminum. I am trying to do something a little more retro than the original interior. Does anyone know of a material that will bend enough to make the curve at the top, yet is light and strong enough to last. I know this is a pretty ambiguous question but I am just trying to get opinions. Thank you
The interior aluminum does add a little structural strength and stiffness to the body of the trailer. Replacing it with anything less than 10 million psi modulus will degrade the performance. Stainless steel is higher strength and modulus but difficult to work with and a lot more money but you could replace it with 1/3 the thickness and achieve the same result as the aluminum.
