I've had two back surgeries, Owned a pop top camper (too small). Tent trailers still have to be set up and you can't tow a boat with one. Go get yourself a nice 3 season tent like Eureka Equinox and some quality cots like the CampTime made in Spokane. Once your off the ground and the heat sucking effect it has on your bones your wife will be fine. I have used the Equinox tent on the Peninsula in 4" per day rains and been dry. Less than $500.00 will outfit you with a nice tent and cots that will fold and fit in less than half your Honda's trunk. URL's follow
