am fulltiming in the farthest north panhandle region of Texas, also doing a construction job. The first thing I did after delivery of my unit (~January 2) was flush all the antifreeze out of the system from the winterizing done at the dealership. I originally planned to live off my FW tank until I could safely hook up a hose, but ultimately bought a hose with a heater at the local Ace Hardware. I then measured the distance from my sewer outlet to their sewer inlet (~16ft), and I went back to Ace and bought two 8' pieces of 3" PVC pipe and two rubber 90's and a rubber coupling, and a clear flushing connector. I filed the quick connect nubs off the clear connector, then put a rubber 90 on the clear piece, I put the first piece of 8' PVC, then the coupling, then the second piece of PVC. I then cut the second piece of PVC to the exact length (it was about 15" long), put on the second 90 into the parks sewer, and added the 15" to the other end of the 90 to go deep into their line. I then went and supported the hard piped system several places and I now have a hard piped sewer that has given me no issues at all even leaving the gray open, and it has been very cold here at times this winter. The other thing I did was got a 100# propane tank to use for the winter months ... the 30's on the unit would not last long in a cold snap like we had here in November. The first 100# tank lasted less than two weeks, but it has been warmer since, so I expect this tank might last a while. I heat with my propane (thus keeping my plumbing from freezing) setting the thermostat all the way back during the day to 55, and usually living with the temp at 65-70 while I'm home in the evenings, and setting it to 60 to sleep (I hate to be hot while sleeping), and wake up and tweak it up to 70 for morning before setting it back to 55 again before work. I thought about skirting it, and no doubt that would have saved on propane, perhaps kept the floor warmer in the winter etc, but ultimately I think I would not have recovered the cost in savings. These units with the "climate shield" packages are made to endure the elements without all the skirting as long as you run the heater in the unit (not space heaters).
