But Gary ... what you have is far from a Class B!
If I had your rig, I'd be boondocking in the real boonies - as far from any blacktop as possible. Of course it's best to camp in the real boonies with other great like-minded folks as often as possible.
I checked out the Roadtrek models at their website. They're nice fancy units and come at high bucks. However, they do have one model I would consider if I wanted to over-spend per cubic foot. I'd have to order it with much larger diameter tires to get more ground clearance, though. ;)
