enclosed underneath of camper

I recently purchased a very well maintained 2002 5th wheel Mountaineer by Montana. I a going from a newer travel trailer (Jayco) tag 2007 but the Mountaineer is extremely well kept and passed RV friend's dealership maintenance checklist. Wanted a fiver but did not have the funds for a newer one. I love the unit and am looking forward to taking it for our first trip. The only thing that jumped out at me was the underside of the RV was not enclosed like my jayco and other newer models. I'm guessing the newer covered units if for insulation from cold weather or critters. Recently camped next to same model but a 2006 and it was completely covered underneath. I guess there is insulation between the metal/vinyl and the bottom of the trailer. Has anyone ever noticed this? I wonder if I could get someone to retrofit a cover for the bottom and what type of insulation should I use. Any reference sources would be appreciated.

    The material used is Coroplast. That link will give you the distributors in your area. It's reportedly expensive. I've heard that Home Depot and probably Lowes can special order it. There is some special tape they use on it as well. Call Coroplast and get the product id for RV underbellies as well as the part number for the tape.

    The best insulation is rigid foam board, the 2 inch material. You can get that at Home Depot/Lowes as well. The RV manufacturers use fiberglass insulation which is fine until it gets wet when it is no longer and good. The rigid foam survives a water leak with no problems.
