"testing" and "rating" aside that "bike rack" bolt on hitch from slee looks mighty strong to me. over in other parts of the world people are bolting hitches to that rear crossmember using the holes toyota put there just for that purpose. I immagined toyota "tested" that crossmember for at leaste a few thousand pounds. I can only reasonably supose that Slee's big ol bumper even reinforces the crossmember. This newer towing attachment/go-through-the-crossmember thing looks even beefier. The only thing to question are the welds and they look darn redundant. Having grown up a farm kid in a huge agricultural setting in Fresno California I can assure you there are lots of home made hitches out there on the road-few that look anything as sturdy as these slee jobs-Not that this makes it right to design your own-just fact-use the chain. and what about all those zillions of home made trailers on the road-do you trust the welds on the neck of the trailer that hooks to the ball? I'm for safety too it just doesn't seem like these slee hitches are the least common denominator.
If someone has used one of these slee hitches and has a resultant horror story I will eat my post-otherwise they look good to me
