dodge guy has been stuck on this issue for a long time.
Back in the day, I camped with my brother a fair amount. I had the Equal-I-zer, and he had the dual-cam. We observed each other's set ups and shared stories. When it was all said and done, we determined that they both worked well and did what they were supposed to do.
I personally like being able to leave the hitch and bars attached to the tow vehicle, but pushed up close to the bumper out of the way. I can drive around that way with no problem. I don't like how noisy the Equal-I-zer can be when doing slow maneuvers in the camp ground. That can be rectified with a little grease though.
