  • Came with the thermal package, which really wasn't.
    • Some additional belly material, screws, and spray foam completed the 'enclosed' part.
    • Plumbed in the missing duct from furnace to underbelly, dropped it in between fresh water tanks. This handles down to about 15F just fine.
    • Found a string of work lights at Home Depot. Poked the caged part up above the belly pan and left the plug part below. 4 75W lights - 1 by black tank drain, 1 by grey tank drain, 1 each fore and aft of the fresh water tanks. This gets us down to below 0 with out any trouble.
  • Heat tape and lights plugged into pedestal instead of trailer.
  • Will make a little sealed plug cover for the work lights before we roll out again.
  • Black tanked closed, grey tank open. Grey tank tends to freeze open and a heat lamp for a couple minutes lets me close it while dumping black tank. They make a valve warmer I could stick on there.
Temps are between 35 and 25 now; heat tape on, lights off, and all is well with the heated underbelly.

I was going to skirt the trailer but unless it gets back down to 0 for an extended period I'm not going to worry about it for now.
Thanks, very good real world experience.

I've gotten that impression. Is there any noticeable help from insulation in walls/ceiling so that the furnace cycles have several minutes between them, if that makes sense. Ours is off for only a very short time if outside temp is in lower 30s and below. We have thermal windows, enclose underbelly (not heated as far as I know) but no thermal package. I don't want to pay for something in our next trailer that doesn't work.
