Tailgate Bike Pad - any experience?

Yep I looked into building my own system our of PVC pipe. Only issue that I have is the tool box being mounted right where the homemade rack would go, hence the problem. I’ve seen several guys make their own , and others used the tailgate pad to haul up to 4 bikes. The pads are nice and your bikes don’t fall out either, despite how it looks. Yes the bike tires are getting larger for sure. I ride full suspension Giant and older model but plan to upgrade in year or so and keep this one as a back up. That bike pad system keeps all bikes upright without getting damaged supposedly. I’m still searching out ideas as well, I can pretty much build most things easily so I’m sure to come up with an option that works out if I don’t go the tailgate pad route either.
