My only concern would be the milage and long drives with how the gas prices are and the fact that I couldn't afford a new or nice one with low mileage. I do agree that it is the way to go in a rual setting where you serve multiple towns and you don't have to worry about going back to the shop to work on anything. Im a big guy so the stand up room is a ultimate plus.
If your not getting the results you desire then change. People change from either desperation or inspiration.
