A lot depends on your current motorhoming needs and habits, home parking arrangements. A's seem to suit many mature couples who stay in nice RV parks, People with kids like the overhead bed (for kids), and a rear bedroom for Mom and Pop plus cabinet storage space and cargo bay of 27foot+ Class C's.Youthful outdoorsy types seem to like short class C's for rustic back country camping. B+ rigs are quite popular with mature couples. Addition of slides adds more interior space but more weight and potential mechanical problems. So it's a matter of camping/touring styles, "taste" and convenience of both man (and) wife. No rig is "perfect", for your changing needs, it's a bunch of compromizes. You will get hundreds of personal opinions.
