I have a 2014 Seneca TS and tow a 2012 Jeep Unlimited. Have towed the jeep approx. 1,000 miles using a Blue Ox Patriot supplemental brake. I have is set on 5 and will try setting 4 as suggested here. The brake only seem to activate only on hard braking, I think that is the way it should function. As others here say, most states require brakes on towed vehicles. Liability sure is a concern it the event of an accident.
I like the ease of set up with the Patriot and so far it does a good job. In ten days we will begin an approx 6,000 mile plus trip to the east coast from CO. our first long trip in the Seneca. Wish us the best! Sam
