I have two Chevy Astro vans. I like them a lot better than the Doge Caravans, Windstars Venture vans etc because of having more room. They drive great and mine do between 16 1/2 to 19 MPG. They're great for just traveling around in also. Like my pickup the visibility is better because of sitting higher than other vehicles.

I carry two 15" Peaveys, my Korg i30, my Mackie mixer, a 2'X2'X2 1/2' case for wires mic etc. my Tenor Sax, mic stands, a laptop, and a two wheel fold-up hand truck.

A trailer wouldn't be a problem out here in the west, the streets are twice a wide as New Orleans, but it would be a problem in congested cities for parking etc.

Think about a van before you spend money for a trailer. Of course if you need to haul drums and a whole band, you may need a dedicated trailer. Are you going to start at 10AM to pick up everyone? Or, are they going to come to your place to load up?

Wow! what a night-mare. Maybe you'd better do a one man band thingy. You'll have lots less head aches and make a lot more money per gig. You'll just have to depend on yourself.
