Im learning much about rebuilding my shasta. I have another burning question for you good people. I purchased a corragated underbelly material from a company,and started install. Are you serious,I had to ask myself. Is this material going to keep the bottom of my tt dry? Much less offer any road damage protection? It looks like painted cardboard. THe company says this material is used on new tt.

I think it makes your TT more aerodynamic, helps to keep varmits out, gives you the ability to have some insulation and cover it up. I do think it will help to keep it dry and protect it from road salts and debris. On my last trailer, after 4 years, I saw no noticeable wear or damage.

I've thought the exact same thing... looks like painted cardboard.

Yes it is cheap, but fairly good at what it is for. If it provides some degree of insulation value by keeping the breeze from directly contacting the real underbelly of your TT and provides an additional partial barier from rodents and pests and stops the road water, etc. from directly contacting the underbelly as well as providing a place to stuff some extra insulation around your tanks then it is worth it in my opinion...
It is also easy to seal with spray foam and Gorilla tape or equivalent.

Where might I get this stuff? Is it ordered online or would it be better to get it from an RV supply place dealer locally?

Clear coroplast has been used in sunrooms for many years. If I were putting this stuff on a trailer, I think that's what I'd choose. It'd be much easier to tell if any rodents had made their way in.

It seems that some of you have the underbelly that is the lowest part of your tt. The underbelly on my tt is laying on top of the metal frame. Then the subfloor sits on that.My tanks are not even covered be the underbelly. Im thinking now of going ahead and closing the whole darn thing in the best I can.

Clear coroplast? Hmm, that would be interesting. Would be an easy way to see if you had a leak or not, that's for sure.

The "under belly" is the additional barrier attached near the bottom of the frame, it is always the lowest part of the trailer. You are seeing the bottom layer of your floor. A lot of trailers don't come with an under belly, it is an additional barrier, in your case it doesn't sound like you have an "under belly".
