That's one reason I chose SunnyBrook (now Winnebago Towables). The only wood framing is in the roof trusses. All the rest is aluminum and steel. I do wish the industry would start using real woof insulation because if it does get wet, it doesn't slump together and make a mushy mess that will never dry out. It won't stop the shoddy practices which cause the leaks, but it will not add to the problem and it's low-impact to manufacture. I like the idea that a siding type trailer is easily repairable without chopping it all apart to replace a laminated side panel. That scared me away too. Not to mention I like the traditional look as well.
