Sorry for the late reply. Been using our Bighorn traveling and enjoying this beautiful country. We had the 25K Air Safe hitch tossed in with the deal on our Bighorn and it has worked flawlessly. It sure smoothes our the ride even though the roads in this country are smooth to begin with.
We have only had it for a couple years and just about 30,000 miles but it sure has done us well.
When going down the road and you look in the rear view mirror you see the trailer going up and down and the ride is smooth.
I'm sure it's not for everyone and I'm not sure I would have paid around $2500 for it but since the dealer wanted to get rid of the Bighorn he agreed to toss the Air Hitch in the deal. After having it, personally I would pay to have one.
That is just my opinion.
Good Luck on what you decide and Enjoy RV'n and be Safe.
Jim
