NCWriter and others sum up our experience with a similar B. We keep ours stocked with canned/dry goods and 'travel' clothes. We don't sit around inside our B all the time and are outside or heading, with it, into town. We have camped for several weeks but with hookups. Our dry/boondocking has been from a day or two to a week. We also use ours as a second vehicle which saves our BMW from overuse in the summer. Going from a 40 ft A class to a B is a quantum leap but it is doable with economical planning and use of the B storage resources.
Best of luck and happy travels BIGDOMINO...
