Robert,
While I agree that things can get cramped, in some ways, you have to be stronger than your challenges, overcome them and be of strong will. I spent some 5 weeks last fall living out of my Tacoma with nothing more than a Snugtop on it. If it were not for the moisture and dust coming through the bed, I would have been fine to a point.
There are astronauts who are training for the long trip to mars, the Apollo moon missions were cramped, you have to be strong. And yes, I know this is taking the aspect of living on the road well out of the realm of just recreation. I have spent countless stormy nights and days in tents on peaks in some 90 climbs in my life, I know how to be an astronaut on Earth.
I will have hundreds of days in my All Terrain Bobcat when my project is done at the end of next year, possibly close to 300 in total. So I am adapting my thinking, reading a lot of fantastic books, making friends, optimizing my cabin workflow to include hygiene, tool accountability and near subconscious routines. I luxuriate in it's efficiency, not in it's appointments.
The reason I could *not* live in a huge Earthroamer is not because it lacks room, but by it's sheer size and luxury of appointments, it makes a statement to me of finish over function. And I *really* don't like the statement it makes to the people I am going to encounter, some living in near poverty.
And I knew Hunter Thompson by the way, his widow Anita and I are still friends. I think he would have chosen the Earth Roamer in red if he were to have hit / live on the road…;-)
