There are plenty of Hams in RV's. you can find a bunch of them, in oh, about 2.5 weeks, about 5 or six miles south of I-10 on the west side of SR-95 in Arizona. Alas, I won't be there this year. However I've found them out and about by looking for license plates
And of course when I put up my flag pole,,, With the night light on top (Kind of a joke, single LED lamp, you can ALMOST see it from the ground at night) I get a lot of door knockers
Flag pole carries 3 VHF/UHF antennas too
