Thanks again for all the input - and you too Mike!
We would not be buying the B to replace our trailer. We know we will be sacrificing function for nimbleness. We probably would never even take it to a CG or RV park. Which is why we think a generator might be a necessity once in a while.
At this point we're not sure if we would use the B enough to justify the cost... We'd be taking it to nearby cities to be tourists and then spend the night in stealth mode parked without any hookups. Also we could use it to visit family about 350 miles away - an aging mom, a professional working son, and various others. We could stay in their driveways with maybe an electric cord hookup. And then we could use it for day trips to the mountains or lakeshore to hike and come back to the B for eating, resting, and then go on another hike.
So - if DH has to bend his knees to sleep for a night here and there we're thinking that would be OK. When going on a regular camping trip to stay at CGs and parks we would still use our trailer and have the TV to get around.
