He makes good point though that when up against the bumpers all the additional load is all on the rails, and more importantly, even though the TB rear crossmember is the first frame location to handle suspension loads, it then needs to transfer force to the huge block of iron, etc cantilevered in front of it, which is handled by the rails and reinforced by the shock towers. Additional bracing is of course good regardless, but the front end structure might a bit more robust as a unit then most give it credit for, IMO.
