dreamingrv..... there are many variables that you will have to consider. Since budget is in the picture, you need to get out the pen, paper and calculator. And crunch the numbers in various ways. Not just the purchase price of the units, but the operating costs, living costs, travel costs, etc.... Do it based on moving twice a week, once a week, once every 2 weeks, once a month, once every three months and so on. Then look at your convenience factor. Depending on how you will travel (move). What about set up ad take down. What if after a few months, what if you decide moving is not for you, but you would rather sit in one spot for a while. Will that extra room mean more to you? And like I said, if budget is a factor, you need to consider that as well.
