Storage is not that expensive, and since you're full timing it can find the cheapest place in the Country for storage space and put your household items there. Just be careful that you aren't paying more for storage than the items are really worth.
I'd like to full time it some day, but there is no way I'm getting rid of everything I own to do it. I can trim a lot, but there are things with sentimental value I'll want to keep. And it may take a 12' x 30' storage locker to keep them. (Maybe smaller if I really downsize.) Not to mention, there will come a time when we'll want to move back into a real house. Don't want to have to start completely from scratch when that happens.
