So I'm looking to put a hitch on my 2012 Equinox LT1 I4. The primary purpose that it will be used for is to attach a cargo carrier for road trips. The only other time it would be used is if I move, I would want to attach a trailer to haul my fish tanks with me instead of using a moving company. I know that there is a 1500lb weight limit and the tanks without any water will be under that weight limit. I see a lot of people use the Curt brand Class 3 hitch and am just curious about the issues with the holes not matching up or is it worth it to just pick up a hidden hitch or the uhaul hitch. I need to put it on asap as we will be heading on a road trip in the next couple of weeks. Thanks for the help!
