Buzz,
Looks familiar. I think I took that picture. Alex's Ford F-250/Lance air bag saddle bracket looked exactly like that at the beginning of the White Rim Trail a couple years ago. To do the trail he just took most of the air out of the bags. Several of those grade 8 bolts just snapped and bent the ears on the bracket. There must be a lot of stress on that bracket, depending on how much air in the bag. Good thing you found it before you got way out there somewhere.
regards, as always, jefe
