I love mine too...even went to the trouble of designing and building a
timer board to replace the furnaces onboard motherboard where the timer stopped working. Much fun learning about that heater. Really takes the chill off fast on cold mornings.
Congrats on fixing yours.
But...it, like all the propane appliances except the refer, really sucks up the propane. I have a 33 gallon propane tank but it's a problem getting a fill while on the road plus the expense for delivery at an RV park is often way high. So what I have is 4 electric floor heaters. I run those instead of the floor furnace. I have them all set on the medium (generally, 750W) setting to avoid electrical issues. Picked up most of them at thrift shops in the summer for pennies on the dollar. Looked for ceramic fan forced heaters.
With those, and with the electrical water heater element, I get 2 years between propane tank fills as the stove doesn't use much, the refer is only on gas between RV parks, and the convection/MW replaces a gas oven. I full time RV. I've drifted away from much boondocking and look for 50 amp RV parks but I can still get by on 30 amp and those heaters, and the heat pump if the temp is above 40F.
