The fasteners used on our cover seemed the appropriate grade of plastic and I took care not to tighten them too much. They are pretty much self locking and only need to be a snug fit on the glass and hinge.)
The plastic hinge bolts sheared on our most recent trip. The Texas side roads were a lot rougher than we were used to. I had never touched or adjusted the plastic bolts in the 3 years we have owned the camper.
I didn't think to contact Suburban, but I couldn't find any direct replacements either. While taking apart the stove top for some other screws that had loosened, I noticed missing and mangled rubber bumpers around the perimeter. These little rubber nubs support the glass and prevent it banging the metal while towing.
Only 2 of the plastic bolts had sheared so I bought some 5/16" short stainless bolts from Lowe's, along with some thick rubber washers, locknuts, and a sheet of clear plastic self-stick half round "bumpers".
I moved all the intact plastic bolts to the hinges that join the 2 glass pieces, thinking those would have less stress than the hinges that join the glass to the back of the stove. I used the stainless bolts and lock nuts on the back hinges, with large rubber washers on both sides of the glass. Using lock nuts meant I only had to tighten the bolts enough to just start compressing the rubber washers.
And I used the whole sheet of plastic self-stick bumpers, replacing the remains of the OEM rubber nubs. I believe the failure of the OEM rubber nubs led to the failure of the hinge bolts, as the glass bounced on the metal rim. I'm surprised the glass was intact at the end of the trip, judging from the rub marks on the rim and the glass. I will be watching the self-stick clear bumpers on our next trip to make sure they stay in place and take the weight of the glass.
just my experiences
