So, seller from that ebay auction on post#2 called back.
These are the overall dimensions of the bus:
Inside headroom: 62"
Considering I might have to rent parking from the city anyway...mind as well go with a full length.
I'll keep looking for auctions/better prices in S.FL, too. Already in contact with a few places... Let's see what happens.
It also looks like I'll go with a roof raise, as I'm 6.0' and I might feel a bit claustrophobic if my head is constantly brushing the ceiling lol
What do you guys think?
