Butch, I have found the same logic on regular ROADS here in ohio. That is one of the reasons I want the Nav - my travels have me in so many areas I am not used to going it helps me get around. On some of my travels it doesn't like the roads I go on at all - miles of single lane farm roads, most not even paved. If I have a general idea of where I am and where I am going I can jump on any road I want and the Nav system compensates, recalculates, and I'm still good to go.

As for the 6.2 in my original comparison - things look like they're holding out OK on insurence so I am getting a new 6.7. That was the best outcome of the situation so I am happy. I have a couple dealers looking around and all the trucks so far are Lariat Ultimate's. I guess thats about the only way to get the Nav. I wouldn't mind an XLT, but unless I order it I'm not going to get it. Once insurence hits I've got 5 days to dump my rental. I don't think a truck can be built in that period of time
