Finally getting the goods to tow our new 2018 Jeep Sahara Unlimited 4 door and can't really decide whether I should spend the extra $100 for the Blue Ox Avail vs just getting the Blue Ox Alpha? Have the Blue Ox base plate coming and the RVIBrake3 and a Light Wiring kit and a Tow Vehicle battery charger. Think I am pretty set but just need to pull the string on getting the right Tow Bar. Any advice or experience would be appreciated!
