Cross Country Trip - What length Class C???

Try reversing the thinking. What is the smallest (therefore, most convenient to drive and navigate) vehicle that you can comfortable live in without a daily firedrill to re-configure (ie turning sofas into beds etc), that also has the cargo carrying capacity to take what you would want for a long trip. We chose a 27' Class C unit with a rear twin/king bedroom, and a real dinette. We sleep in the back and store 'stuff' and gear in the over cab bunk. We spent a total of 13 months on long trips over the last 2 years and are confident our choice was good for us. We are nimble, wholly self-contained, and we love our little house. Would not want to be any longer, and we don't need the length. It's a personal decision, but do consider what you 'need' vs the many bells and whistles that really aren't necessary for a simple life on the road.
