Well, mine is a 2000; the Ultimates are insulated very well. The holding tanks are enclosed and heated by the rear LP furnace. All plumbing lines are inside the coach. There is another floor under the floor you walk on, between them is the plumbing lines.
The main concern is the wet-bay, which is unheated as far as I know,, but I always operate the MH self-contained during freezing weather so there is no city water hose or sewer hose or valves to freeze.
Your main heat-loss area is the windshield and windows, plan now what you will insulate them with; aluminum-faced bubble wrap works good. I bought a left-over 8' wide end roll from a pole-building builder for about $20.
You are right to be thinking about an external LP tank, as both LP furnaces burn LP pretty-quickly.
If you will be in that same place for 4 months I would contact an LP business and request they set a 250G tank, then have that Extend-A-Stay(not very expensive on ebay) hose ready for them to attach their tank to your MH. You might want to have the Extend a Stay already installed at home.
