160 pounds sticking a few…
160 pounds sticking a few feet out and up on a bike rack can easily put more torque on the hitch than 1100 pounds pushing straight down or 11,000 pounds pulling straight back. So both numbers could be correct. But still, even the flimsiest hitch around should be capable of supporting way more than the weight of the vehicle on it. Snagging trailer hitches on stuff is just a fact of life when driving on anything besides perfectly flat roads.
