I was in Mississippi visitng my oldest over the weekend. Parked next to a 2001 Dually, CTD. And of course had to look a little. The **** thing had a Splitter switch on the stick . I asked the guy if that really was a what I thought and he said it was. He bought it used, so did not know what the brand was or what it cost. He said he towed a 35' 5th wheel camper and the splitter was great.<br><br>Anyone ever heard of this? I tow nothing and would have no need for one, but I thought it was pretty neat!!

 

Might be a US Gear overdrive unit available through Camping World. Attaches to rear of tranny.<br><br>Bill
