Motor home heating

l" as you know by previous posts, we decided to change our Caravan for Motorhome. WE are lucky to be able to park it on our property. With the caravan we used to leave the heating on when it got down to freezing even though we had winterised the van, use to set it at 6 degrees on the truma digital screen not so on the motorhome as l will explain. With the motor home it will be a little different as we intend to use it at least once or twice a month. l have experimented this week, l set it on the ultraheat at 500 kw on setting 3 on Auto on the fire if that makes sense to you, a little different than the truma 3 system. Do you think it will cause a problem to the system using it twenty four seven or should l invest in a small portable fan heater, l always check the Motorhome everyday to keep a check on any issues that might arise. One thing l don't do is to drop the water tank l leave it a 1/4 full, and also the hot water tank, is this wise even though l have the heating on, obviously it won't take long to fill at home if l did drop it. l have the the flo jet system that blows the residual water out of the caravan but it wont work on the motor home as the tank is vented, if you know of anything l have missed, do please advise.
