On mine, a 2001 model, the bumper is aluminum, and the tabs are aluminum. The lower mounting tabs are two 90* aluminum angles, inserted from the back-side of the bumper, and welded along the top and bottom edges.
From your pictures, I can see the remains of a rivet on each side of the hole, so I suspect yours were not welded. That may have something to do with why yours broke off, because those two jack mounts are subjected to repetitive bending stress when loading the camper. When you back the truck under the camper, I think most of us tend to continue until you feel the front of the bed actually touch the bumpers on the front of the camper. It doesn’t take much pressure from the truck to put A LOT of stress on those tabs. Being aluminum, they readily bend. Do that a few dozen times, and I can see those two rivets getting broken. Over the nearly twenty years I’ve owned my camper, I’ve straightened those tabs twice while doing other repairs to the rear jack areas.
Here’s what mine looks like from the backside of the bumper. This is on the passenger side.
The outside view of the driver side. You can see it has a slight bend in it.
