Yes, all good on my end. I seen about 2 weeks of -35c highs (-31f), for the most part we were around -25c (-13f) lows.
I did eventually skirt my trailer (1x2 framed 2" R10 styrofoam panels), cost only a couple hundred vs the $6k for the canvas type skirting. Albeit not quite as aesthetically pleasing, it served its purpose well. due to the size of the space and the plumbing arrangement i divided the skirting into 2 sections, lead axle (fresh water tank) to the front of the trailer with a 1200w heater, and lead axle back to the forward side of the fuel tank (this area houses the plumbing to the hot water tank and kitchen) with a 600w electric heater.
im a procrastinator, so of course i waited till the first night that it hit -20c and i froze the water to the rear of the trailer before i decided to skirt LOL. Thankfully, pex is extremely forgiving as far as freeze/thaw cycles, no harm done.
ive been pretty surprised that i havent really burnt an outrageous amount of propane. I do run a 600w space heater in the living area as well as another in the garage with the door closed between garage and living area (furnace not ducted back there). i run off of a ~120gal/420lb propane pig, generally get it topped up every 5-6 weeks at a cost just shy of $200. I cant complain about heat, hot water, and cooking for less than $200/month in a stinkin trailer in the winter!
