We’re all thankful that the mystery of the failed Bulldog coupler was (at least apparently) solved and without serious issues. I was beginning to wonder if there was going to be a sudden rash of coupler failures coming our way. Like several others have said, we have never heard of any Bulldog failures. When I purchased my trailer I didn’t select the axles, springs, or coupler at the time of order. Thankfully, I’ve not experienced issues with any major Oliver supplied components. Probably can’t say that for the majority of stick built campers. Although with lack of maintenance I think that I have heard of even a heavy duty axle having bearing failures.
