Throwing this out there in case anyone is considering doing something similar.
I decided to make a rack to store our kayaks in the garage that would free up enough space to also get a car in the garage.
I used some scrap lumber I had laying around, plus a couple of PVC tubes that rods had shipped in. I did have to buy a little bit of 1x4 lumber, but you could substitute almost any type of lumber.

This is what I ended up with. It's sized to be wide enough to fit my wife's Tupelo underneath, and the right height to slide my Tripper 12 directly into the truck bed.

The Tripper 12 has two "channels" on the bottom of the hull, I attached a couple of old PVC rod shipping tubes at the right spacing to ride in these channels on the hull.

I used a 1 1/2 inch hole saw to drill holes in the PVC, then a smaller hole and lag bolts with washers to fasten them to the rack.

This is my wife's Tupelo 12.5 slid into the rack on the C-TUG cart.

The rack is 6 feet long, so the kayaks overhang both ends.

This is the Tripper 12 going from the pickup onto the rack, these should save me some back pain.

I think I found the perfect crate to use with my orange Jackson Kayak.
