The places I like to go are meant for camping, not hotels. (Someone pointed this out).
I have great memories of many campgrounds or campsites but only a couple of great hotel stays and those were in cities where I will still choose hotel.
The cost per night on a camper goes down the more you use it. I mitigate that as a working man by keeping the price down on the camper. In retirement when I can use it more, I'll bump up. We had a pop-up for the last ten years. Looking to move up to a. TT in $15k used range
I echo the many who said not having to pack/unpack is a major convenience of camping.
Last, don't eat out much when traveling regardless of mode but an RV makes it easier with more options.
