What do you folks think of aluminum sided trailers?

Mine has been perfect. Wood frame, aluminum sides, rubber roof. 13 years and going fine.

While aluminum sided RV's are more susceptible to hail damage I have no issues with aluminum siding. If I were interested in a given RV assuming it was in good shape, aluminum siding would not scare me away or negatively impact my decision.

Buddy of mine has an older Springdale. He hates it. Always something denting it. Accidentally hit the sidewall with what ever and it will dent.
Pro's. Cost.
Cons, less insulation and usually but not always lower end finishes.

We had several corrugated aluminum RV's. All leaked because of the undulating shape of the siding. It was impossible to stay ahead of the water intrusion, rot and mold. Had to take one of them straight to the dump.
Personally, now that I've had a couple of hard sided RV's (which have never leaked), I would never go back although I understand it's a price point issue for some.
They also have made some flat aluminum sided RV's that I think would be great.

I haven't had any issue with mine, aluminum sided and roof.

even if the paint is damaged, aluminum won't rust. it won't de-laminate like fiber or composite

it will hold on to every dent and ding, but I don't get worked up about that.

Pro: light
con: don't do well in a hail storm, and a bit harder to get washed with siding

Honestly when I had aluminum siding I was happy and never really thought about it. Once I had smooth siding I liked the "look" of it and was easier to keep clean
