Sure is substantial looking and sounds interesting.
I didn't know that OEM receivers can have excessive movement. Do they have more play in vertical or lateral direction or both? It would be interesting to mount a camcorder under our truck and see what is happening.
There is a lot of lateral play between our Reese shank and OEM Ford receiver. I installed a Blue Ox Immobilizer. I've only towed it once at the end of the season on a short trip and it *seems* to be helping a lot but won't know for sure until next season. That Torklift would be a nice upgrade as far as movement goes but at around $1K would be a tough sell with DW. I like that you can you an add the 48" extender with it and have 1200 lbs TW. I can see a use for that ourselves.
