Towing mmy '06 Liberty for 9 years.
Used a body shop to install brackets; their labor rates are lower than rv shop. SMI Air Force One but would consider the Stay-in-play today. Roadmaster tow hardware but would consider Demco today. The Demco bar just pivots sideways for storage, not lift and pivot. I drilled 1" holes in the lower tail light housing for new tail light bulbs and use red LEDs.
Don't forget to wire the license plate light. Got stopped one night because no light when my sloppy connection failed. I used extra LEDs to the license plate; similar to this one
SuperbrightsLEDOh, I too use a dumb key for the ignition.
