First, thanks to everyone for the input. I'm really enjoying this community and all of the knowledge being shared, so thanks again.
So, the question has become moot after the weekend and some shopping around. In the end we traded in and went with a 2016 3500 Lonestar CC 4X4, 6.7 Cummins with the AISIN trans, OEM Tow package and short box. We got a fantastic deal on the trade, in fact coming in $2k over what we expected and then got some fantastic rebates etc. Does anyone know about a little thing Dodge does if you have a current lease? They rebate you an additional $1000!
We have a Toyota lease on a Corolla and the finance guy surprised me when he asked me if we had any leases and then told me about the extra $$! All in all it was well worth it for the piece of mind and now we not only aren't close to the edge, we have room to grow should we ever want to!
Ultimately we are planning on becoming FTers within the next 2 years with our home base being southwest corner of Colorado near Telluride. So those facts and with all of the mountain hauling we will be doing were all factored in to the investment.
As soon as the 5er gets here I'll take some pics of our setup.
Again, I can't say thanks enough for the responses.
