I traveled 40+ states over 6+ years full time in a nicely converted Eagle 10. I was turned away at a number of RV parks. The first one shocked the hell out of me as I was driving a rig that looked nearly brand new. New siding, paint, raised roof, RV windows etc. I converted a 1980 shell in 1994(?). They looked at the registration and said "sorry no rigs over 10 years old". I started getting a little forgetful at that point. It was converted in '94 then it must be a '94 model....
I was also turned away at a number of parks because my dog was overweight.... I found a number of parks that had weight limits on pets. 25-40 lbs depending on the park. Yapping ankle biters=good. Good natured, well behaved & quiet Golden Retriever=bad....
I had the most issues in the Southwest US. Las Vegas sticks in my mind as probably the worst.
Gotta love Walmart parking lots....
