I'm just past 2 years myself of full timing (excepting 2 months last spring) and I hear all of what you are saying. If you aren't mobile, living in a camper can be a downer. On the other hand, when your out and traveling there is nothing that can touch it. I expect that this fall I will be finding a more normal living arrangement, but then again, I thought that last fall.....
Its funny, how I feel about full timing depends on the day I have been having. If the day was bad, I feel like a failure living in a camper at my age. On the other hand, on good days, I feel like I have beat the system and am living the good life way ahead of everyone else
.
I guess in the end I figure there is a time for everything and so I will go with the flow. Maybe your time for fulltiming is over for now, maybe you will want to do it again later on. Or maybe not, who knows
