Insulating the floor???

I put a 1" thick piece of the pink foam board that I picked up at Home Depot. With the 3200 lb. weight of the camper on it there has been no compression or any damage. Problem with wood, any wood including marine plywood, is that it absorbs water. The pink foam board does not absorb water or rot or mildew or delaminate.

Best part is that it is "light as a feather" as compared to the weight of a piece of 3/4 inch plywood of the same dimensions. Much easier to remove the foam panel and store when the camper is off the truck.

Also comes in a 2" thickness for more height and more insulation of the camper.

I have a non basement Lance and I use a thick rubber mat and the 2" blue insulation. Cheap enough and makes a noticeable difference on the floor. It also gives me the clearance on the cab. I am going to make window covers and insulate the compartments this year. All other peoples ideals and eagerly adopted by myself.

I added a rubber mat. My thought it is it is nonslip and will provide some insulating ability. However, the sides are still going to be exposed and represent probably more surface area than the bottom by quite a bit.

We made a removable carpet piece for winter use. Installed it over a thick foam carpet pad from Home Depot. Huge difference in temps, plus it feel nice to have carpet in the winter. I also have an approx. 18" x 30" heated rubber foot mat. If you have shore power - awesome!

I am looking into the thin, under carpet heated pads they sell now. Those weren't even available a few years ago... some of them can be cut to size to really get a custom installation.

We could have it better with external rigid foam insulation, but the carpet was easier for me to do by myself b/c DH has had enough "camper mods" and has declined my "offers" to let him "assist" me anymore this year LOL :)

When I had a Coachman 9.5 sd, I just put a piece of 4X8 foam on the pickup bed before mounting the camper. It worked fine the whole time I had it. This included many trips during the winter in western Maine.

Hi,

If you will have shore power there are electric heated carpets.

The camper Jeff & Kelli method is pretty much the same thing that I did - only my "insulation frame" hangs from the camper.

Whatever you do, be sure to get some foam that does not soak with water.

I don't have a TC but, I think Camper Jeff & Kelli has a great method for insulating the floor.

Here is what I did to insulate my camper.

5/4x6 treated decking with 1" foam board "chewy center". Much lighter than plywood and insulates. The wood perimeter solidly supports the camper edges.


Insulated compartment doors.


Insulation attached to the tub sides and up under the wings.

I have also installed insulation inside the TC on the walls inside the cabinets and appliances where I was able to install it.
The insulation made a great improvement when winter camping.

Also get a couple cheap rugs for the floor. It's warmer than vinyl.

Personal experience:

Instead of using plywood, I used XPS foam board. I have done this for both my campers. I built a frame of the size of the camper floor from simple 1x2 wood, and filled the area in between with 2" XPS (Extruded polystyrene foam) board.

Sorry, I have no pictures right now.

The stuff is pretty weatherproof and insulates quite well. It is hard enough to carry the camper. It is also inexpensive.

In the first camper, a Lance 915, the difference in floor insulation was quite noticeable.

The new camper, an Outfitter Apex, has a basement. So there is no direct effect that I could notice.
