I do a lot of shuffling between OKC and Bonners Ferry Idaho and catch a few shooting events that cause me to load up a lot of guns. Wrestled with it for a couple years with various solution before coming up with this for the back of my truck. Had a guy ask about it so collected some pictures I took along the way to send him. Thought it might be of interest through the original idea and the first two modifications. Excuse the craftsmanship. Could be done better but like most things I'm about to pull out before I get down to business.
I'll post pictures of the modification (changed from firm-board insulation to wood and put a top on it for additional storage space) in next post.
These were taken at initial construction and the rifle supports were made from firm-board 1 1/2" insulation.
This was the start. Got the two caps on either end level setting in place inside the cab, then put the floor on.
Then put a support between the drivetrain hump and the middle of the floor. Trial and error there.
Than (not shown) put another cap on the end to glue the saddle notch firm-board insulation piece to.
I didn’t like the rifle stops after the first year so changed them when I decided I wanted to replace the insulation and put a top on it.
The whole unit slides up to the barrel ends and then the two bolts drop in to pre-drilled holes.
