how to insulate the bottom on slide

I have a 1998 fleetwood wilderness 26H and would like to have some ideas on insulating the bottom of the slide for the winter. The camper will not be moved. Thanks

One option would be to skirt the entire trailer with the skirting coming up to the bottom of the slides. It would keep the entire underside of the trailer warmer.

I have seen fellows building insulated skirting using sheets of plywood, 2x2 with pink insulation. If it is really cold and you are staying for a while it would be worth the effort for the resulting comfort and fuel savings.

Welcome to iRV2.

Gordon has covered the best way to insulate the trailer , BUT if you're in an RV park there may be limits on what they will allow.

In the past I used some 1" foam insulation board up against the bottom of the slide. It is barely, if at all, noticeable, and in my case I used a couple of slide supports to gently hold it up against the bottom of the slide. You could use anything you like to keep it in place. Did a nice job of keeping the slide floor much warmer. And it is cheap enough to throw away when no longer needed in case you don't have the space to store it.

depending on where you are keeping your rig.

the rectangular straw/hay bails... all around the bottom of trailer. then cover with the black garden weed preventer plastic.

I have seen this a few times..

If you don't want to look like the Beverly Hillbillies then th addition of foam board insulation would be th logical choice. You need to insulate the slide bottom and also around th slide seals. You lose more heat from around the seals than through the floor. What ever you use to seal around the rubber seals remember you need to remove it so use something that will not leave too much residue after removing.
