We all have our own comfort levels. There isn’t one better than another.
When I started looking around on Cheap RV living many years ago I had bought a really tiny fiberglass trailer. I think it was about 8’ long. I needed info on storage in very small spaces.
Bob was in a cargo trailer then I believe and I started gleaning info from his website. I don’t believe there was a forum at that time.
Over the years I kept buying and selling and got bigger, then smaller, then bigger again in the types of trailers and RVs.
I only suggest that before you buy take a hard look at your comfort levels. Don’t look at something too big or small and think, “That might not be too bad”. If you are already thinking it then that’s probably not going to be ok for you.
I guess the most regrets I have heard over the years is not being able to stand up.
I’m in a behemoth now for medical reasons as an adjustable bed was necessary for John. So I guess that became our new comfort level.
