...We're in the process of looking for a tow trailer (this could be just as easily a 5th, too) to install in the southern region as a "base camp" for us and our truck camper rig (the truck camper will be for off-roading to various remote sites to boondock, from time-to-time; and for picking up groceries at the home base). We'll do this in the southern US until our health insurance costs climb out of reach (we're Canadian snowbirders heading into our early 60s). We investigated buying a fixed trailer at a fixed park(s), but this could be fraught with too many negatives (selling it eventually, long distance; increasing park fees; 12 months of rent opposed to 4~5 months RV lot fees; growing out of the fixed park (what if we grow not to like the park?); permanent electric monthly fees for fixed unit; etc, etc, etc). We found that many RV parks will store a towable/mobile trailer for peanuts on site for 7 or 8 months. And, If we wanted to keep the trailer, we could haul it back home eventually (or, sell it easier than a huge fixed park model with all the mobile home park $obligations baggage).
When our US side health insurance climbs out of reach, we plan to rent an inexpensive condo (as a base camp so to speak) in extreme south Mexico for 4 to 6 months, bringing along our truck camper rig (to off-road to Mayan ruins in the Yucatan outback), by dead-heading it across the USA (no matter what our age, it won't cost much in health insurance crossing the USA to Mexico in a week, from Canada).
FWIW, we have a few Canadian friends that do the above and love it. I think you'll be surprised at the number of Canadians that have the exact same setup going on. Even the Yucatan part, but in that case they currently fly down and stay.
