Has anyone purchased a hitch and plug and play wiring harness from canamspyderaccessories.com? I bought a harbor freight tag along trailer today for My 2015 RT limited. My dealer wants about 730 dollars to put on the oem hitch and harness. I watched a few videos from the above website and liked the fact that the hitch can be put on in about 5 minutes and the harness that is plug and play can be done with very minimal removal of panels. I know theirs is about 500 dollars which still saves me over 200 dollars. I saw others cheaper but wasn't sure if putting on their hitch was just as easy. I seen some wiring harness where you connect it to the battery directly but that looks like a few more panels to be removed.
