Beds Hot and Cold weather

wow. Some great info in such a short period of time. Thanks everyone.
Currently, I do not own an RV at all. Just in the looking stages right now. Don't want to haul around something too big with wind drag, weight, etc.

My Apache served me well from 1975 until 1995 when I sold it for $300 less than I paid for it. So for 20 years, it only cost me $300 to have it. What a deal.

I do not want a canvas trailer but I do want a pop-up and Trailmanor fits the bill quite nicely. You could feel the cold coming thru the bed matress on the apache in cold weather. Seems like the Trailmanor has the same problem. Just thought they might have insulated the underside but I guess not.

I will probably buy sometime early next year and believe it will be the 3124KB. For those who use a heating pad of some sort, do you place it under or on top of the matress?

Thanks everyone for all your help.
