I don't know about the OP
But we are one of a great many couples on this forum and in the country who do not "go camping" with our RV/TT.
We LIVE in our rig as we travel the country. Yes, we occasionally go to places like a beautiful USFS Campground 20 miles down a dirt road from any services.
But most of the year we need access to the internet at most campgrounds we visit. We don't even get paper mail any longer. Our mail forwarding service scans our mail and forwards us the images via e-mail.
If you want to get on your high horse about what "camping " should be like, fine. I'll just say you should try living at your home with no internet, cable, TV, for 250-300+ days a year.
I'm not trying to make people conform to my idea of what camping is/ should be.
Would appreciate some understanding that we all have different goals.
For the OP, if I wasn't exactly clear above - I provide solutions for those issues myself. I never depend upon an RV park to have them.
Just a FYI, the very best RV park WiFI/ internet I've ever had was at a remote state park, which just happened to be near a telephone company long lines microwave tower.
