I bought a new gas over a used diesel for a floorplan with bunks that fits my family, but also the budget. We have young kids and plan to weekend and vacation in it, hard to find a used diesel with a floorplan like the 364 TS from Georgetown.
I was quite pleasantly surprised by the lack of noise so far on the V10 with 6 spd trans. I hear about yelling at your passenger, etc but so far on level ground I'm at 2050 rpm for 60 or 65mph so cruising speed is quiet. I have not driven mountains, but in rolling terrain it's has yet to downshift more than one gear and that is not often.
I had a diesel F250 so I understand the torque curves and benefits, but the v10 is more than adequate for what I need. If I won a free one and got to pick a new gas or diesel I think you would still know he answer though...
