The draw bar is just fine. I do wish that it had come with the pin and it’s safety clip. These items did not come with it. A little disappointing on that point. 482233


Comments
Philip, Thank you for your review. If you need a standard pin and clip for this ball mount I would recommend part F-4. If you would like a locking pin I recommend part RH2-XL.

I spent around $175 for a what I thought to be a complete hitch installation and apparently the lousy $2.00 receiver pin was too much cost for etrailer to include. So now I get the pleasure to travel 25 miles to buy that pin locally. Amazon looks better every day. 640180


Comments
Our description states that the hitch pin and clip or locking hitch pin is sold separately. This is to allow our customers to choose the approiate lock that they may need, or mayalready have for their accessories. If you would like the standard hitch pin that would be used for this item is a F-4. Or a locking version as part C23517.

This part was a disappointment. The design is very poor for the application on my car. If I installing as intended, the trailer hitch is far too low to the ground. When I install it upside down to get more height, the tongue mashed into the bumper cover. I stuck on some foam window seal material on the hitch, where it makes contact with the bumper, in hopes it won’t damage the finish on my bumper. Either the tongue needs to be Linder, or the hold for the lock pin needs to be repositioned. 791548

Etrailer was recommended by other Mini Cooper drivers in Anchorage, AK. I needed a trailer hitch in a rush as I need to relocate back to the lower 48 because of COVID-19. Jennifer at etrailer was so helpful in getting the right hitch and all the necessary collateral pieces for the install. I was concerned that it might take too long to get the hitch, but Jennifer made sure I had the hitch within 5 days! I am happy to say that the hitch is installed and I’m ready to hit the road! Thank you so much, Jennifer and etrailer! 784500

I purchased both the trailer hitch for my 2007 Honda Element and the wiring harness. The products came shipped to me on time and packaged very well. Installation of the hitch was extremely easy. Only thing I would recommend is to use a drill bit file instead of a drill to enlarge the hole to mount the hitch because it doesn't really need to be enlarged that much more. The wiring harness was also extremely easy to install. I suggest using the videos on YouTube because those helped to make things a little clearer. I am extremely satisfied with the products and value that I received from this company. I would recommend it highly. 744533
