The trouble with leaving the heater going 24/7 is electricity. Those RV heaters will drain your battery in one night. Fine idea if you're able to hook up to eletricity though.The skirting idea good too but who wants to haul a truckload of straw bales with them.My advice if it is really cold, drain and don't use it.
anyone ever heard of rv antifreeze being bad for hot water tanks? I thought about running some through the lines.
If you have the "newer" hard rubber hose for pipe(I don't remember what it is called), it will probably be o.k. The weakest part is the outside shower, the shower is all plastic and will break pretty easily. The new hose is very strong, I have froze my lines before with no problems and have seen another rig freeze up without any problems either. Not on purpose but it happened.
