Well, I went a different way. I went with TransK9 kennels to protect my babies. We did a trip to the mountains 2 weeks ago and the seatbelt harnesses tethered to the floor looked uncomfortable, and while they wouldn’t have flown across the car, the harnesses weren’t really designed to be used this way. I thought about racing harnesses, and them breaking backs if they weren’t attached to a horizontal bar rather than the floor.
I’m planning on mammoth trips this winter, and moving to Texas next year, which will require a long road trip. This should do nicely. So far no noises driving around, and the quality looks awesome. Ratchet straps will be coming tomorrow.
Once someone comes up with a reasonably priced plate system I’ll pull the third row, take out the shelf, and drop in a drawer system.
