Motorhome Winter Strategies

Unlike last February, I have a spare 30/ 15amp mini tandem breaker on board here in the motorhome.  The Coleman roof top unit is a heater/ air conditioner.  Right now, at 48°F outdoors, I have the heater set at minimum in my 31 year old Itasca Sundancer.  The indoor temperature is reading 66°F.  There is no wind to speak of here.

Last year, I used 14 bales of hay to insulate the outside bottom of my motorhome.  This year, I have some kind of padded material and it's outside is kind of foil like.  I'd even call it "space age?"  But I just now had a thought.  What if inside the shielding, I could stuff the bottom to make it more solid?

What I have coming up is I have to replace the hot water tank.  Then I'll have to search for gas leaks.  I'm certain that there's one at the stove.  In case things go wrong, I need to be able to bypass bad systems, or directly plug them in one at a time.  That could at least entail the installation of a liquid propane coupler from the outside to the in so that something like a 20# tank can remain out.  Of course, a line from the inside port would connect to the hot water heater, stove/ oven or heating systems.

Or could I install shut off valves at each appliance and just use the main input line?  If I did both strategies, I could accommodate a LP heater.  A cylindrical shaped object that costs about $150 present day.

New Faucet Installed: Bathtub

I installed a new faucet in my bathtub/ shower, but I reused the old shower hose and head.  The new faucet flows better, but I think that there's some clogging in the old shower line?  I do not understand how, but the electical reading for the propane is indicating a full tank.  I have to do some electrical testing to the liquid propane/ explosive gas sensor just to see if it's getting any power to begin with?  I'm unable to find battery powered replacements, so this is going to have to be wired to the converter.  If I can figure out what's going on with it, the next task will be to determine what's going on with the hot water tank?

The sensor has an automatic shut off feature when it senses gas in the chassis.
