2026 Custom Trail Boss & plastic.

I don't know about previous years or other models but the 2026 Custom Trail Boss fuel door and fuel door hinge is plastic leaving no where short of the bedside to stick the fuel cap while refueling. I used a metal plate for a cell phone magnet. Maybe include this for future purchasers, if not $3 buys them on Amazon. Also, I didn't trust the sticky back that came in the metal plate so I doubled it up with Gorilla Glue extreme double sided tape.
