I was wondering if somebody can give me some advise on Insulating the bottom of my travel trailer. I bought it used and it had been in a flood, someone had cut all the Insulation off the bottom of the camper. There is no water damage to the inside of the camper. I was thinking about having someone spray foam under the bottom, are buying some industrial Styrofoam and gluing it to the bottom of the camper. The camper is a Springdale, and it had Insulation and a black thick plastic under the bottom before someone took it out. Any suggestions would be deeply appreciated.

I would not suggest spray foam because once it's on; it's on. You cant access plumbing, wiring, etc in case you need to.
Why not use fiberglass insulation and install sheets of the plastic that was originally on there. Use Gorilla tape to seal the seams.

If you can access underneath the flooring. I would suggest glueing closed cell insulation foam board there. For the rest of it, Owens Corning makes a fiberglass batt insulation that is encased in plastic ( no worries about it getting soaked due to traveling in the rain). Corroplast is the corrugated plastic product used to make signs and used as the belly pan. Some stips of aluminum and self drilling-self tapping screws will secure it in place.

I think you said this TT was flooded. Be sure you get the wheel bearing repacked and have the brakes checked.

I would use foam board to insulate the floor with. One day I plan on building a sort of enclosed underbelly between my frame rails and adding foam board to augment the little bit of insulation I already have.

I would check with a dealer and put it back the way the factory built it originally.

I would like to thank all of you for all your comment. There is no water damage to the inside or underside of the travel trailer. The water just got higher to get inside insulation and had to be removed because it holds water. Thanks again

If it was in a flood and the insulation had to be removed, how could there not be floor damage?

Here are some links to underbelly material and coroplast:

underbelly material

coroplast

I think the underbelly material might be found at a local mobile home supply/repair facility. As someone already mentioned, the alternative coroplast might be found at a local sign company, but maybe not in black color.

Foam board or fiberglass batt work fine. Another less familiar insulation is bubble wrap. Bubble wrap has the flexibility of fiberglass while resisting absorbing water such as foam. Surprisingly, it has equal or better insulation value to similar thicknesses as foam. I think it may be most expensive as a downside.
