Not to turn this into a discussion on gas vs diesel, but to me it seems like there is a lot more regular maintenance required on a diesel and you have to be timely with it. Regular (3,000 mile?) filter replacement for example. Whole new set of technical matters you really should/need to learn.
Me, I just want a truck that I can get into and turn the key and away we go (with warmup), like a gasser does. Won't kill the engine if I ignore or forget the service intervals. Easier to find gas vs diesel fuel on the road. Cheaper repairs. Easier to find a mechanic who knows gas engines if you have a breakdown when out on the open road. Not to mention the significantly higher purchase when new. One good plus to a diesel is that you can leave it sit all winter and not worry about the fuel going bad.
For a day or so, we thought about a new diesel truck, but can't justify the higher purchase and maintenance costs and diesel-specific things you have to stay on top of. Seems like it would take a lot of miles to get a payback on the purchase and maintenance cost of a diesel.
The Ford V10 is rated to tow 12,500 which I think should be good for most folks, unless you have a big rig that dictates a higher towing capacity.
