Very nice... Congratulation!
I would have bought that truck...
I have a Smarty Junior inbound for my 2011 3500... Couple of folks I know claim the Smarty is best... fuel timing, transmission shifting, MPG. Don't know, but thought to mention it.
I am doing TWO 7 pin connectors on every truck (maybe 3 on some that get abused). Trailer Brakes matter a WHOLE LOT. Might even do two cables on some trailers.
Hope the elk hunting went well... post some pics.
