My wife and I are now both 75 (and she is handicapped) We have been camping all our married life starting with tents and sleeping bags on a small motorcycle and working up over the years to big motorcycles and towing a small cargo trailer.
At one time I designed and built a folding camper that was big enough for the two of us. but just barely.
In 2013, I gave up motorcycles and bought a GMC terrain with the v6 for the towing power. (rated at 3500lbs.) Then we bought a 2010 Palomino Yearling Y-4124
pop up camper that looked like it would do the job. And it has. We've been using it 5 or 6 times a year since then to go camping by ourselves or with the kids and grand kids. I took it on it's first trip and then added brakes and a AC unit and the controller myself. I have also installed the friction type anti sway bar. The unit loads out at 2800 lbs. and works for us. I will admit that as I get older I keep thinking about a TT for ease of setup, but we have decided that if we(I) get to old to handle set up then we are going to be done with camping. But we are going to enjoy it as long as we can.
