I know the back support was rusty but I found out how bad today!! I saw when I got this truck(my 87 plow truck) and new I was gonna have to fix, but I was gonna wait till spring. HAHAHA! I never tried to open gate, didn't want to mess with it. well, I hit a bump and, well, I guess the right side of gate wasn't latched. it fell open on the right side and the left side stayed latched. bent the #$$@@#$ out of gate!! made it home though!! used 2 jacks to lift body back up so I could close gate and shoved 2x4's under back floor!! guess I'll have to fix soon!
