yes it still works fine.
I am going to tow a 6x12 uhaul in March. Will post back on experience.

 

i actually ended up going with the stealth hitch and it was set up great on my 21 E450 All Terrain. kick to open also still works.

 

I just finished towing a uhaul 6×12 tandem cargo trailer for a 1400 km round trip. Had at least 2000lbs in it. All good. No swaying or noise.
I got about 11.4l/100km on the loaded leg and about 14l/100km on the empty return due to higher speeds.
I got the taller hitch receiver so the hitch and tongue would be 18" high and nice and level.
would recommend.

 

Hell yeah this is awesome. I expect to move out of state soon and got a Stealth Hitch installed for this exact reason. How much did you save vs. renting a U-Haul truck?

 

I saved a lot, not sure how much a truck would cost. I returned the trailer back to where i rented it which saved about $600. Total cost of the trailer was $204 cad including tax and $40 of insurance for a 4 day rental. The truck would have used way more gas too.
