Not to be a big downer or anything, but are we sure that Robogames will happen again next year? Dave ran a great gig this year and I'll go back for sure if he has it again, but there was one definite and another near-miss box breaches this year so I would expect arena and insurance costs to go up again next year. It is an awfully expensive deal already and I'd hate to see you go in on a vehicle and have that not happen. Of course, you could come to motorama then!
8 people and 8 big bots plus tools is going to take up an awful lot of space... the school bus idea is probably closer to the size range than an RV unless you add on a trailer. Just Gloomsday took up the entire folded-down back seats of the van we were driving around. The saw was between the middle seats and we had maybe a foot or so of extra width on the sides once it was assembled... It was big. Would you be able to rent something for just the trip? It seems like it might be do-able for a once-a-year thing.
