Trailer Hitch and Wiring Recommendation for 2012 GMC Terrain

Question:

What is the difference between the “classes” in trailer hitches.. I have the 4 cylinder 2012 Terrain. Should I get the class 2 or 3.???... I probably only be towing a small boat and trailer less than 1000 pounds...

Basically the higher the hitch Class the more towing capacity it has. But the big difference between Class II and III is that III is a 2 inch hitch which is the most popular size due to capacities and accessories made for it and Class II is a 1-1/4 inch. If you plan to do any towing with your 2012 GMC Terrain I'd recommend going with the Class III.

For that you'd want the etrailer part # e98865 which is a custom fit and our most popular option. It's also priced great too. For trailer wiring you'd then want the part # 118494 which is also a custom fit.

Since you wanted to do some towing you might be interested in etrailer ball mount kit # 989900. It comes with 2 ball mounts; one with a 3/4 inch rise or 2 inch drop and one with a 2-3/4 inch rise or 4 inch drop. It also includes a 1-7/8 inch ball, 2 inch ball, hitch pin with clip, and a storage bag.

If the ball mount kit does not include a ball mount with the right rise or drop to tow the trailer level, check out the link I have included that explains how to measure to choose a ball mount to tow the trailer level.
