I've picked up at Redstone (I have canned engines for Wallew and DRat). The trip is about 3 hours each way for me. The engines weigh about 800# in the can, according to the stencils. I don't know if they will load onto a pickup, and the can would probably not fit between the fender wells. I would recommend a small 2 axle trailer, the can is a little top heavy. I would be afraid of flipping a single axle trailer unless it was around 7' wide. Take plenty of straps, and 1/2 dozen 1/2x3 bolts, nuts, and washers. Most of the cans I saw at Redstone were not bolted shut, some only had 2 bolts and no nuts.
If you get one cheap, I can make the trip. I have a forklift here at home to unload with.
