Do all MHs with the hot water heat systems have heated floors, or is that just a unique feature on some brands? I've heard them talked about but don't see them advertised in the features very much.
I do have heater hoses going under the mid-floor. Does that count? Heating tubing under the floor are easy and cheap, but also have disadvantages. I read that some truck campers have that kind of heating while using water heater. Now - having only 1 heater to do all tasks why that sounds inventive?
