Campgrounds .. No , not so much . Rv parks ? Especially the nicer "resorts" , pool , activities rooms etc , near larger towns / cities ? yes. Since we started full time 4 months ago and moved our way across the us we have been asked ,when calling for day of reservations , 3-4 times.
. In much of the monthly rate info ( we don't stay monthly) of many popular parks you'll see 10-15 year rules. Most aren't strict on this if you provide a photo of your non cousin Eddie rig. We have tended to stay at slightly higher end parks so that tilts the scale some.
The conversation I had with one park owner ( manager)? Was that I'd see more of it as park owners try to fight a increase in run down live ins Those who don't move but can't afford or qualify for a apartment because they tore up their last place, his words not mine . His opinion was they are presenting drug and theft problem for management. I tend not to be that pessimistic but I'm not the management either. And I don't stay in Rv parks that look like that , making his point I guess.
