welcome
Me too, just like yours. 2 weeks in the garage. my son came home and said I need to look at the garage door. when I went outside, the bracket holding it on the 2x6 had come off. only thing keeping it off my truck was it was connected to the door opener. was scared to do anything. only 4 inches from front of truck. was able to get help, we lifted the one piece door up and supported it. got the truck out of garage and did repair.
not sure how to post pics. any help
missed the back fold down unit under seat with tradesman, but it was so easy to make one. 25 dollars and carpeted floor now. folds out just like factory, my dog loves it.
