Has anyone here had to replace their bulkhead cooler? I sucked a rock up into my tunnel this weekend and killed the tunnel cooler and the bulkhead cooler also sustained some damage. It looks like a huge pain to replace. The bolts on either side of the cooler don't look bad but having to drill out those rivets on the belly panel to access two larger bolts doesn't look fun. Looking for some guidance from anyone with experience. I'm no stranger to wrenching on stuff, but there is a point where its too involved.
