Great responses thank you all!
I am going to see about renting an RV, starting with and F-53 to see how we like it over Spring Break. I also found a couple Axis/Vegas models for rent but they are a bit of a drive just to get to the coach.
On the boat/RV comparison - bingo! That is precisely why I struggled to understand the RV pricing structure. Now it makes more sense.
One the plus side, if size is not really the determining financial factor (as it is in a boat purchase), I guess I should count my blessings because more options are available to me.
Of course, now I have the "too much on the menu"problem.
Thanks again.
