Broken Billsteins, tailgate and (Recent trip photos)

Hey Yall, It's been a long time. I hope everyone is doing alright. I'd like to share my recent trip photos and ask some questions regarding shocks and tailgates as well. Me and my Brother went on a 1000 km trail to the Northern borders of Mongolia and Russia. We were hauling our dirtbikes and general camping on the taco and had a great time. Unfortunately on our way back, some asshat in a Prius compact decided to merge without signals and I ended up in the roadside ditch right into a 6ft jump, luckily the car did not flip or roll but it did break all of my shocks(Bilstein 5100's front and back) and because of the dirtbikes on the back, my tailgate was partially broken and the rearview camera cable snapped, as soon as I got to the city, I replaced my shocks with a new set of Bilstein and am looking for a possible solution on the tailgate. My main questions would be.

1. If I can somehow fix my tailgate, would it be possible to rewire the camera with the old wires, or should I get a whole new set?

2. What is your recommended solution for Hauling Dirtbikes without too much damage on the bed frame? (Possible solution for two dirtbikes)

3. After an accidental Jump, what else should i look out for in terms of in case of anything else that has been damaged?

Let me know what you guys think and Check out the photos

Thank you.
