24 foot box truck!! in Bellingham, WA

1993 diesel GMC Topkick 24 foot box truck. Mileage in the mid 4s but its running smooth and strong, tons of life left. No parking brake. I drove from southern California with a very full load and had no problems, just need to have some blocks or a curb. Minor leak in box but I might have time to fix, only needs a little caulking. Both batteries are brand new, she starts up real nice. The lift gate platform was cut off to save some weight but everything else for the lift is still there.
