I see many, many, Starlink antennas at the 2 Thousand Trails parks I stay at in the San Diego area, maybe as many as 1 in 4 RV's. These parks both have the Jabba net WiFi service available at about $40 a month, but I have found their service performance pretty spotty. Starlink RV users that I have talked to mainly depend on it for on the road remote internet businesses and jobs. I also see the antennas (with the $160 a month service) on the RVers illegally camping along the side of the road.
I use the best ATT unlimited cellphone service for my Iphone XR bluetooth linked to my laptop for about $70 a month (including $25 a month veteran's discount). Cell signals are 5 bars at 1 park (with a local rancher having ATT and Verizon cell towers on his property literally across the street from the park), but not so great at the other park. I have a telescoping conduit (20 feet) with multiband cell antenna outside, and a Wilson MyFi 4 band bidirectional cell amplifier inside, which ups the 1 bar unamplified to 5 bars in that park. I also use Dish network for my TV, and currently pay about $140 a month for that (before my $160 a 7 month season MLB extra innings baseball package).
