In the past we often frequented the Ft Rucker, AL campground; with Senior Pass it's $13.50 /nite. Water, power included - lone sewer dump at entrance. Nice bath house w/ community room that provides wifi. The grandkids enjoy the numerous low-flying copters.
For me the very best was it has an area where the dogs can run/ play / swim (off-leash).
No problems with our former 32 footer but the newer 42' one catches branches using their u-shaped pull thrus - causing scratches that didn't buff out.
We have an August reservation at Destin (FL) Military Campground coming up.
