We have FMCA, Good Sam's, and FCRV (since DW's Sister and Brother both have 5th wheels)
We enjoy the monthly rallies with our FMCA club, the annual Eastern Area rallies and occasional National rally, if it is east of the Mississippi.
FMCA has some great benefits included in the $40 per year cost, and still has a magazine.
Good Sam's is great for the campground discount, and we got a lifetime membership back a few years ago when they were offering a deal for Veterans.
FCRV in our area is just about defunct. We keep it up so we can join an occasional rally that my in laws go to...
