Do I need to be concerned with the 2 bolts that my swing away tongue hinges on? Not posing the question for any particular concern. My Shoreland'r trailer uses 2 bolts as the hinge for the swing away tongue. Just wondering if these will see wear and tear. The clevis pin doesn't wear, just wondering if the bolts will and no, I can't check them because, if anything, they will need to be cut off to check for wear. Trailer is a 2013 and is towed every weekend 8 months a year.
