Make sure you tell your insurance company your going to use this for a party bus, my insurance company (GMAC) asked me about 10 questions about what I was going to use it for, my other insurance company (Farmers) would not insure it but they did give plenty of advice we discussed "party bus" hauling friends to "the game" my agent said if I dont declare my use and their was a accident I was on my own because I violated my terms and conditions, he also said if their was personal injury's I would probably lose everything I owned and would have liens put against any of my future purchases, basically people would follow me and my money the rest of my life, bottom line the days of the "party bus" are now over, think hard before you think your doing your friends a favor by driving them to "the game", he also touched base a little on "open container" laws if you get pulled over by the cops, and having the proper drivers license for hauling people to and from even if your not charging them it matters because of the size, in a van you would be ok...
I bought my bus for a conversion into a toy hauler and RV I was cautioned on taking 5 friends on a ride trip also..
The thing my Farmers insurance agent kept stressing was the IMPORTANCE of telling your insurance agent EVERYTHING you might be using the bus for, he said its quite easy for insurance company's to deny claims because you were outside the intended use.
