Chapman in Philly is super legit. You'll need to hit the rebates to make the dollar amount work out for you as shown online, but my purchase prices are always fantastic - I hit most if not all rebates.
I bought my 2016 3500 High Country and 2016 Callaway from there this year, and a box truck, and probably something else because there's still a few months left to go this year.
