We have a 2011 Jeep Liberty. We would like to hear from anyone who has this specific vehicle and find out which supplemental brake they are using. We have a new Class C and need to tow this specific jeep. I understand there are many different ones out there and have researched them but would like to hear from someone who owns the 2011 Jeep Liberty. The floorboard near the divers seat is very narrow. We need to know also if anyone has a solution to the problem of the battery discharging as you tow.
