Toyota Tacoma Tent Camping Sleeping Platform Build

I just bought a 2018 Toyota Tacoma and want to get into camping in it. I found and bought a Rightline tent that goes on the truck bed, which I have seen it on with the tonneau cover folded up.
The space between the wheel wells is less than 24 inches, which is 24 inches , and the width of 2 airpads I have. In my truck bed along the sides, I see there is a lip to add a platform that would give me the width I need.
So, with a little Muskrat Engineering, I built a platform I could sleep on, with an extension to add length. I also gained storage underneath. But I then encountered a problem that you will see in my end review. Maybe you can help me out as overall I like the setup.
Also if you like backpacking, and outdoor activities please subscribe to my channel, hit the bell notifications, like and share my videos.
Thank you.

I love your extension over the tailgate. Lots of good ideas in your video!

You could use the flange option for all the way around I like that idea.
