Best newbie advice I've heard is not to get too ambitious with the renovations right off the bat. Get it clean (your dirt is cleaner than their dirt), roadworthy (frame, coupler, wiring, axle
, tires), and dry (test for leaks
with a garden hose sprayer, being careful not to spray directly into fridge
vents, etc.). You can always use it as a hard-sided tent even if appliances, electrical
, or plumbing aren't working. A good polish outside and some simple, inexpensive cosmetic touches inside will make it feel like yours until you're ready to tackle more extensive projects.
Above all, unless you are an experienced rehabber with a decent workshop and plenty of spare cash, I wouldn't recommend attempting a full gut-and-rebuild on the first round.
How about some pictures for a start?
