I have the AUH with the OEM puck/gooseneck ball. As much as I like the AUH, I have also second-guessed my purchase thinking I might consider the goosebox if I had it to do over (mostly due to the clean bed when unhooked). However, the people I travel with have traditional 5th wheel hitches. In a pinch, if I need my trailer towed by a buddy's truck, I'd be screwed and have to find someone with a gooseneck ball. With the AUH, all I have to do is remove the king pin adapter (two bolts and loosen the set screws).
