Well, I think I have figured out what I'm going to do with the Pull-Pal, but not enough time to fab things before the next trip. Will probably carry the beam sideways on the outside rear of the roof rack, so that I can stand on the tailgate to deploy it. The spade looks like I can carry it on top of my stack of MaxTrax that are already on the rack. Width of the RW1400 spade is a little greater than the width of the Maxtrax, so it will nest nicely on top of the stack and be padlocked onto a couple of studs.
My temporary solution for the upcoming trip is an electronic keyboard case by Gator that I found on Amazon. The case is their 76-Note Slim (GKB-76SLIM). Width is perfect for the RW14000 spade, and length is a little more than I need, but it will work. Case holds the complete Pull-Pal and has enough room for stuff like a cable damper, gloves, recovery straps etc. It has internal velcro straps that cinch everything down, and I will strap it to the top of my cross-bed tool box in the bed of the truck. Not a permanent solution because I often need that space for other gear, but it works for this trip. Bonus is that the case is near perfect for a stack of MaxTrax and a couple of recovery
straps, so will eventually go into the other truck.
