I’m a ham and RVer and I’ve travelled with a 2 meter radio for decades. I’ve seldom found local repeaters to be useful for finding a campsite, as compared to other resources. That being said, I have met many hams on the road by simply monitoring 146.52 Mhz . Using this national calling frequency, I’ve have tips on campsites that proved very useful. I’ve met hams in my travels in the U.S. and Canada, but this is not something you can count on.
Trying to find an active repeater along any route always seems to be too much of a bother. I only wish more hams /RVers would monitor 146.52 Mhz while on the road, or even in campsites.
