I had a 31" Swamper mounted on a modified stock mount for a couple of years. The mount held up fine, but the hinges really took a beating and began to clunk a lot, and then I began to notice small cracks in the sheet metal near the door opening. Finally built a swing away mount, problems solved. BTW, I still have the modified mount, will fit up to a 32" wheel / tire combo if anyone needs one. Photo at my flickr site.
