The newer Fords are far more "cushy" than the older ones. I actually don't like this but it seemed Ford was trying hard to appease the white collar crowd versus the blue collar ones. I have the F450 and was somewhat surprised at how much it sagged versus my '09 F350 SRW. In other words, your ride will be fine. You may even want to throw some air bags on it later on just to level things out. If the pin weight of the HD isn't one of the heavier ones, then it won't be too bad anyway. My pin weight is around 3300 - 3500 lbs.
As for price, my MSRP was $82,000 and I paid in the low $50,000s. If you're in Virginia anytime soon, RV Outlet will be your best bet pricewise.
