Draw-Tite 24915 Sportframe Class I Hitch came from Amazon. Easy bolt-on accessory. eTrailer.com even has a video on installation. We are using it along with a bike rack to bring our two bikes with us on the road. Hitch can handle up to 200#.
Waiting on parts to add remote entry. (about $10 on eBay). Again, I will be installing. We save a ton of money doing these projects ourselves.
