We plan to do our own testing, but if 118's design lasted the season in Aerial Assault, my initial hunch is that our more conservative design will too.

That round tube you see on their drive was actually only to fulfill the rule that there should be no "unsupported" side of the bumper greater than 8" After seeing it at competition it really didn't even support the bumper but it was there only to pass inspection.
I'm not quite sure how they mounted it but my guess is they just tapped the ends of that tube or round stock and bolted it onto those large 2x1 uprights. IIRC the inspectors made them lift their robot by their "Bumper supports" (The round stock in the screenshot) in order for them to pass the inspection proving that "Those actually do support the bumpers". They used those large holes with large threaded bolts attached to the bumpers to mount their bumpers to their robot.
If I were to use what 118 did, I would in fact just use a piece of aluminum rod or even thunderhex shaft that is tapped to do what they did in a similar fashion.
