It's so unrealiable that I had to go buy a Land Rover to make myself feel better.
Okay, sure they are old and need a bit of fixin every now and then, but you can get the engine rebuilt for less than a set of tires on the taco. Just make sure you get an AAA membership with the 100 mile free towing. You will use it.
My recommendation is to go for a late '80s or early '90s Vanagon instead of a bus. Find a rust free one out West and drive it back east.
Oh, and when I go surfing I usually take 2-3 boards and pick the best one depending on conditions and spot. I usually only take one when I take the car. The other nice thing is changing in and out of a wetsuit inside the van in the middle of winter. Priceless.
