Buying a used RV? Never thought of doing that. BTW The prices that I have seen are way off on the spectrum. Some are outrageous, while another I found to be pretty fucking affordable.
What you're gonna have to factor into is gas, and gas ain't what it used to be pre-'00 ($0.91 a gallon) . At 2,700 miles (Whorelando to BR, NV), and an RV doing 10 MPG, you're looking at 270 gallons, at $3.50, $945 just in gas. Don't forget it is going to take a min of 3 days, so thats 3 days out of school/work, and 9 meals. You're looking at an easy $1000 just to get there. Oh and the what if, what if you blow a tyre, RV won't start, etc.
There are so many what ifs, and cost prohibitive factors that it makes it illogical.
Did I forget to mention the cost of the RV, and what you are going to do with it once you arrive back from BM?
$1K per person, 4 people, should be enough for airfare, BM tickets, RV rental, supplies, and food.
Haven't confirmed it yet, but this is what I'm working with at the moment.
