I've got the Sidewinder, would have never thought folks would be inserting and removing the bolts/wedge like that. The shop I use, uses their forklift to push/pivot the arm on the hitch to the side and then with a ball on the end of one of the forks, places it in the cavity under the turret of the sidewinder to maneuver the trailer.
With all of that said, I will be adding the bolts to my toolbox in the near future. Towed the trailer to a local state park on Friday (the 13th). Engine developed a ticking sound, variable with engine speed, lifter is #1 on the differential diagnosis list. I had to drop off the truck at a local Chevy dealer near the park, returned home last night in one of their loaner trucks, trailer remains at the park. They open up the engine today to confirm repairs, fortunately, it is only an hour from home and likely covered by the truck's 100,000 mile warranty!
Had I been able to find a loaner with a 5th wheel hitch (and long enough bed) I might have been trying to scrounge up some bolts of the proper grade.
