It would be a great experiment if Fonotour would build a high end RV park near one of their future developments (say in Teacapan for example) with all the amenities that one of the best US RV parks has. They could increase the revenue by offering the resort amenities for additional $$. They could bring in a premium rate and see what happens. Not sure how much $$ the resorts make on all-inclusives after the airfare and profits are taken, it would be interesting to do the math on an upscale RV park daily rate vs. the (net) money made on an all inclusive room minus the food, room upkeep and bar costs.
In terms of the boondockers, there will always be folks with high end RVs that want to camp for nothing (saw lots of these in the desert in California), but there is always a market for upscale RV parks. We noted that in Yuma in the $500 per month parks that the occupancy seemed to be around 50% this past winter. We stayed at an upscale park in California at triple that rate plus electricity, we asked about getting a site on the edge of the golf course and were told that we could get on the waiting list for someone to pass away before a site would become available!
