Early last year I realized I really needed a cargo van, after a couple of years with an Odyssey w/tow hitch for the bigger gigs. I did my homework on the available options and landed on the Mercedes Metris - price is actually comparable to similarly spec'd vans from other manufacturers, it carries 3500lbs and can tow 5000 - so far I haven't had to tow anything, it LOVES being packed to the ceiling with gear!
I did a 4-day camping festival in June, packed all the gear plus our camping gear, with all of that it was able to easily maintain 70mph through the NorCal hills and got 22mpg on the way & 24mpg on the return (elevation change made the difference) running on cruise-control the whole way.
This Sunday I had two gigs, one 10 minutes from home so I hauled out & set that one up, made sure the engineer had everything he needed, and went home & loaded for my other gig.
It's a pleasure to drive, hauls all the gear I need, gets good gas mileage, and fits in a normal garage. Highly recommended.
I know a new one isn't in the budget stated in the OP, but used ones are out there & the drive train should be good for >300,000 miles with regular servicing.
