I have been thinking about insulating the floor above the basement in my 345rf. I was wondering if there was any reason why I should not do this? I was thinking about using 1 1/2 or 2" foam.

Or even insulating the heat-run if you have one to keep the heat up there.

No reason at all not to do it. We insulated the basement ceiling in our trailer with 11/2" rigid insulation and then covered it with bubble wrap. Really helped keep the bath/bedroom floor warmer in the Winter. Several manufactures now insulate it.

We insulated ours as well and in addition removed the foil pipe and hard piped the heat runs so we would not have to worry about poking the pipes. Biggest change for temperatures in the bedroom floor however we dropped the skin around the pinbox under our bedroom and addedrigid insulation to that area in addition to the factory insulation .

We did ours and it made a big difference in keeping the cool and heat inside instead of leaking into the basement. Absolutely no reason to not do it.

It will depend on the design and how cold of weather you will be exposed to. My 2010 5th wheel Cruiser would be one you would not want to do this if you are exposed to below zero conditions for long periods. My waste tanks are under the basement and rely on heat from the basement area to prevent them from freezing. I was helping a friend fix a heat vent problem on a Montana last week and in his case insulating the basement floor would be OK. The Montana had a heat vent duct about 1.5 to 2 inch in diameter run into the area of the waste tanks to keep them from freezing.

I agree, its a good idea, I purchased 2 sheets of 2 inch rigid insulation with foil wrapped already attached. It was on my list of winterizing jobs.... that list never got completed... It'll be one of the first things I do in the spring.

Several years ago I used foam between the joists to insulate and replaced the foil ducts with insulated ducts. This helped the heat situation some but I didn't think of adding the bubble wrap also. May add that if I feel real energentic someday! The factory ducting design is very poor for getting any heat to the bed/bath area in most modelsfor sure.
