The van is nice. Stuff stays dry. The old Chevy works better than the old Ford. They just require less repair.
For open trailers, the Florda Custom vans turn out real nice. Low abuse factor, sometimes low mileage, etc. Full size Chev or the Box vans from the rental places. Check out any of the quad tired rear ends real well before you buy one tho. They get used hard, and have a very high replacement cost.
For enclosed trailers, the Excursuion is very nice but costly long term. ovewr 100K.
