We're in the process of planning for becoming full timers and had settled on a 5er around 42', however we've read in a lot of blogs where they regretted going long and we're looking at downsizing. We don't plan on using the 5er for general camping as we have a hybrid for state parks etc. as the 5er will be our home shouldn't we err on the side of livability. I'm interested in hearing the opinion of the long timers. Many thanks.
