Aluminun skin thickness

[LDK]

Hello all, I've talked to a few suppliers of sheet aluminum (sign companys) here where I live and they can get it at .040 thickness. Is that a good thickness or should I go thinner or thicker??? I can get a 4x10 white enamel finish at $68.00 a sheet. Being the rookie that I am I would appreciate any and all advice. Thanks guys Larry

that should be a good thickness i read some of the builds and thats what they used.

I'm going to use .63 because i'm building a offroad tiny trailer

Yep, 040 is a good thickness (even for an 'offroad' trailer) and easy to work with. And the price is a fare price.
