We did a three year stretch of 60-80% of our time spent in a 33' Winny with one large slide. We still snowbird in it, four months a year, and have no issues with the amount of space. We both are far from pack rats, and at no time are the basement areas, or any cabinets, 100% full. The only caution I found, when shopping for a small to medium size Class A, was that a lot of the 30' and shorter rigs had ZERO countertop space. It was ridiculous! Kitchens with a double sink jambed tight to the stove and nothing else. To us that's a pretty obvious deal breaker, but there are lots of folks that get by with that arrangement. That said, a well laid out 30' A, or even a smaller, can make a great full time rig, and there are tens of thousands of folks on the road with far less.
