CB or Ham Radio good to get in contact to other RVers?

I use an Icom 706-MK ham all band rig. I monitor 146.52 and scan 2 meters sometimes, not much there any more. I also have 146.52 and 146.55(for the go to freq), cb channels 9,19 and 13 frequencies, marine 156.650 and an occasional local rv park or area freq. I can only broadcast on the ham bands legally, if CB communications is needed I grab the Cobra 39 and do that.
I do use 75 and 40 meters occasionally, 40 being my favorite.
I still enjoy ham, just wish it was as busy as it used to be.
