Has anybody had a diamond plate stone guard applied to your travel trailer? My vinyl type stone guard disintegrated when water gift behind it. The diamond plate would be a better solution.
I used a stud finder and found some studs. Alas, they weren't all right where I wanted them and a couple screws go through the inside behind the bed where I used some large washers/nuts. I did use a liberal amount of sealant on the screws/holes.
Might look for a gutter or siding guy locally that would have a sheet metal brake.
