Will use etrailer again and again. Fast delivery. My Curt A16 head upgrade came with no damage. I've ordered several times and If there are issues with the products delivered they make it right and then some. There QA sessions are terrific. 873429

Well built but I not like pins I think that is a easy fix 799530

I had to replace my standard 5th wheel hitch with this because my RV has a Reese Revolution system. Hooking up is smoother and feels more secure. Very smooth towing with no noise or slack. I suggest getting the wedge kit . 782026

Works great! I am sorry I did not buy it in the beginning. But, I didn't know what I was doing and the original sales person (not e-trailer) was not very helpful. I am very happy with the service I got from E-trailer 683088

What a great experience. What could have been a disappointment, Kim and the other Customer Service personnel were great. A damaged box resulted in a missing handle for my 5th wheel mount and etrailer staff made it right and expedited the missing part to me so I could pick up my new camper on time. I am sold on etrailer. Thanks for all you do!!!!! 461177

No one else had this at the price etrailer afford 422879

I love the product. Thats why I bought a second one when I destroyed the first one. I contacted Curt and we never could resolve the problem being able to put the Teflon plate between the fifth wheel in the hitch. I called to see if they could help you with that problem and they were puzzled. Sent numerous pictures so it must be on my end but I dont understand why the original hitch I purchased work very well and then I replace the head and the Teflon plate will not work there just not enough room but as far as the product goes I think its the best one out there its quiet no clunking. I hear all kinds of stories but this one works flawless.
