John...I can only speak for what I have found around here in No. Cal...but typically .040...on a roll at 103" wide or in 4x10 sheets...but I know you can get it in .030 pretty easily...check with the truck trailer repair shops, you can get it on a coil and it's lots cheaper, but it does take more care to make sure you don't mark it up...the really nice bright polished anodized comes with a plastic film on it...not too sure on it's thicknesses however...Doug

JP, the most common is .032/.040...some have gone upto .060, especially if used on a roof with no substrate under it..

I work in a steel warehouse(nowdays, known as Service Center,lol).But one thing I was taught ions ago, right off the bat was...Steel sheet is measured in gauge ( 11 ga.,14ga.,16.,ect...).Aluminum is measured in decimal (.032,.040.062.ect...). I ain't tryin to to be a wise ass, just sharin a lil knowledge.By the way,while we're on th subject,I have .040 Al. for the roof.Is it necessary to skin it first with 1/4" ply the sheet? Just wanderin.Any info woud be appreciated. Thanks. ---Moe---

Thanks for the info, I never knew that aluminum and steel went by different measurement systems.

I used the .040 Al on my roof with 2 layers of 1/8in ply underneath. Probably could have gotten away with just 1 layer but no big deal. Some people say that you can put the aluminum directly on the foam but I am not one of those people.

I've heard that you can put alum directly over foam, but it's much easier to dent. So I would suggest at least 1 layer of 1/8" plywood.

Thanks Asian & Mike for the input.My plans are for .032 on walls & .040 for the roof.When it's free from work out of the scratch & dent pile,and the frame material was about the cost of a bucket of dirt,you seem to get whats available. I have seen some construction with & without skins on the roof.Thats what I like about this site so much,the way info info is shared and armchair opinions are abundant. My next task is to figure out the axle width,then I'll be off on a date with a Lincoln & a hand full of stick rods. Thanks again y'all ---Moe---
