Sorry for the very late reply....when we towed our 95 wrangler with our 22' coachman class c we did not use a brake system and, although we probably should have used one, we never had a problem. Now, with our 2013 wrangler and 2013 Class A we do use an Rvi2 brake system and like it very much. The current Jeep is heavier and I feel better knowing we have the brake system in it.
Again, sorry for the very late reply.
I was reading your post on towing a Wrangler. I have an 89 Wrangler and want to tow it with my 24' Class C. I have the towbar, wiring and cables ready to go but wanted to see if you had an aux braking system in your Jeep when you pull it?
