Listen to rockhillmanor. A fully self-contained TC is the SUV of RVs... go anywhere at anytime. For heavy travel around the country in practically any kind of weather, you'd be hard pressed to find a better alternative. It fits wherever the truck goes, height considering.
As a full time unit, it's severely lacking. With space at a premium, some highly desirable amenities are sacrificed. That may be ok for a younger guy. However, there's barely adequate room for one f/t person as long as nothing is under foot. Add another person and there will be a lot of "excuse me(s)". With two 40lb. dogs, you'll have to go outside to change your mind. I'd hate to be half asleep and have to navigate to the bathroom at 2 a.m.
A power failure during the summer, particularly in the south, would be a huge concern. While I've camped at government parks 95% of the time, I've come home after work to a sweltering camper in both public and commercial parks. Due to that fact, I won't consider a pet until retirement. These are the musings of an old guy with a lot of TC miles, having been there and done that. Hope the perspective is of help.
