I'm working on my 67' Shatsta 1500. I've got a 1/2" plywood floor laid over the steel and 2x frame. The interior is built directly on the plywood floor.
I could...
1)lay 1" strips, insulate between them with foam and put a new subfloor on top. This would effectively lower everything by 1.5" inside the trailer as I don't want to alter the trailer height nor do a frame off restoration. I'm 5' 9" so this could work.
2)insulate underneath the trailer subfloor between the wood 2x and steel frame. This would be easier and add less weight but I'm concerned about water getting between whatever I use and the wood subfloor.
Anyone ever solved this problem?

I usually work with what's there, so if it's not insulated to start with, I leave it as is. I'm wondering if you could have a company spray insulating foam when the time comes?

I insulated the floor of my teardrop style camper by gluing foam insulation to the underneath side of the floor. Also made some plastic "fender washers" by taking my largest hole saw and drilling through some "race car" plastic I had, then ran a screw through it for extra support for the glue. Didn't want the pink showing, so before I put the screws and washers on I removed the plastic film from the foam. After that, put a couple coats of Rustoleum enamel on it, it's held up for 6 years and 32,000 miles. The foam takes the paint real well with the film removed. I can probably come up with some pictures if you like...

Does it not have a belly pan? My 65 has a belly pan and I just put 2 layers of the silver backed stuff between pan and the floor.

I think gluing some foam insulation to the underside and then painting seems pretty reasonable. I could use the pink stuff which seems more durable than the white kind. I could Glue it on and then spray some expanding foam around the edges for a better seal. If gluing on the underside I could use 2" thick stuff for better insulation. Thanks for the ideas guys! |

Thanks for the ideas guys! what about a spray foam? Not like the stuff in the can but something more commercial. But it would suck if you had to ever get it off. |

Keep in mind that if there is any, ANY, gap for water to get behind the foam it is going to be trapped and will cause the wood to rot MUCH faster. While no experience with what you are thinking I just know from working with boats and gaps in a seal like that can make them rot much faster.

I'll stop and get pics of my foam & paint belly on our li'l camper on my way home from work. |

I’d probably try it without any insulation. If you have good plywood and seal all your joints before you put down the flooring then I’d see actually how cold or hot it gets and if it would even make a difference to insulate.

Again, cut foam for tight fit, peeled plastic "skin" off & glued with liquid nails? to the bottom. Made large plastic fender washers with a hole saw, installed screws for extra support. Painted with Rustoleum enamel (2 coats, took paint very well & didn't melt it), sealed around edge with caulking (I know, looks dirty now, but it has 32K miles on it too!)   |

The point kudzu made about water getting up under is valid indeed and would be a major concern. Perhaps this is a project to wait a season or two to undertake depending on how hot or cold the floors feel as aslmx suggested. I'm trying to do as little as possible to fix up the trailer so this would be a somewhat time consuming distraction. |

Actually did mine when the floor was upside down.  |
