My bet is that if you do not have a leak with in the 1 year warranty, Keystone will deny any claim. A staple is not a problem, just a problem waiting to happen.
Keystone will not fix a problem waiting to happen.
A example would be my spring hangers that are outside the specs of Dexter axle. Keystone said it was not a issue that would be covered. The spring hangers are almost 1/4" wider than what Dexter requires for it's 1 7/8" spring that Keystone used on my trailer.
This look right to you?
