We have an 40' Class A & a R-vision B+ 213. The B+ (21') is fine for a "vacation rig". We spent from May 19th until August 4 this year in our B+ on an Alaska trip with friends in their C (24'). But I was very glad when we changed the B+ for the A in storage. We have talked about going back a few years in age to a Foretravel or Newell with one or no slides, but to full time in a small 21' motorhome, no way. I prefer to explore after we set up without tearing down. The biggest pain w/o the big rig was no Splendide washer/dryer and no toad.
