Hello...I've been reading this website for several days and thought I'd join. There are a lot of really interesting replies to questions, and you folks seem to be very knowledgable. We are retired (US citizens) and have been RV'ing in Mexico for a couple of years now during the winter months. This next seasonwe plan to take our truck/trailer to the Lo De Marco area (45 miles north of Puerto Vallarta) and stay for 5 months. Then we'd like to head up to the central highlands for several more months. Perhaps returning to the USA for several months (or maybe not). Am interested if other RV'ers are doing the same thing. We'd have to get an FM3 for extended stay. Anyone else out there doing the same thing?? Any advice?
