emok, when my '06 Highlander Hybrid Limited was "sandwiched" on the local interstate while we were on the way to the airport for a vacation a number of years back, the dude in the Caddy behind me took a beating from my hitch-ball for sure
, but more importantly, that extra structure reduced the level of damage in the back of my vehicle.
Now on the JGC, the OEM hitch receiver is structurally part of the bumper system, so it's not "adding" a whole lot of extra structure, but presumably, that part of the vehicle is already beefed up to handle the extra load of towing and tongue weight. 'Should still be helpful in the event of an accident.
