@Scheherezade – yeah, I think not only a trailer but I also would have to trade in my current rig for a smaller/lighter amp. Right now I wouldn't feel very comfortable with an old fender tube amp bouncing around.
@Newspaperguy – usually what we do is borrow somebody's van/car. If there's enough room we all pile in but usually there's just enough room for the driver and maybe one other. So the rest of us bike. Public transit/taxis really aren't a viable option as we have so much gear. We're a 5 piece band, have four amps, guitars, keyboard and drums.
@Roody – that is AWESOME.
I suppose I have to come to terms with reality and realize I need at least a smaller amp and a trailer... guess I better start saving

Nice to know it's been done before. We probably will end up with a vehicle to call our own at some point but a man can dream, right?
