Enclosing older TT undersides

Hey all, I've been seriously considering enclosing the underside of my 2006 Jayflight 31 BHS since we brought it home...has anybody else undertaken this feat? Don't know if I should use a fabric or sheetmetal...thinking fabric so that it will breath and cut down on condensation. I live in Texas after all, and the Humidity here is crazy. Since we FT now, looking for any way to help with heating/cooling this beast...right now temps are getting up to 104 some days, and this past winter we had three pretty decent freezes, at least for Texas. As always, any helpful hints or advice would be welcome!!

Yeah, the humidy is horridible (sic) down Houston way. Way more so than up in Abilene where I lived for four years (the longest decade of my life) and Abilene felt like a swamp compared to my home in AZ. You might want to look into coroplast, the corrugated plastic that sign makers often use. It's easy to work with and is both light and rigid. It's pretty much the same stuff that Jayco and some other RV makers use to enclose their underbellies (they use black).

Enclosing the underside will not buy you much unless you camp in very cold regions. Then it acts the same as wrapping your pipes, keeping the freezing wind off your plumbing. I've read from a couple of owners that claim you get better mileage towing because it reduces air turbulance under the trailer, but I havn't seen any real world number to substantiate thet claim. If you decide to do it, there is a corrugated plastic type material that's made for the task and won't add a lot of weight to the trailer like sheet metal would. JMO

You could look into spray in foam. A two or three inch application might make a difference.
