I am not sure any topic draws more heated debate than the old "gas versus diesel" which I think often boils down to intangibles more than the oft stated power differences, mileage, etc. Simply put, I think more folks buy diesel not based on need, but based on want.
Our last truck was a dually diesel. Great when it was towing or hauling, but less desirable the rest of the time which was most of it. Some folks don't mind walking a mile after finally finding a place to park, we do. Cost of maintenance versus gas, ouch. As a daily driver, sorry just not very agile at the bank or the local water hole.
So since we don't need the power and didn't feel a couple more miles per gallon made up for the difference in purchase prices, this time around we went F350 6.2 SRW gasser. Yes it eats more fuel and yes it downshifts more on the steep grades, but it is a much better fit for what we need a truck to do and I when I change the oil it is 7 quarts versus the 14 of oil.
In the end, you're writing the check, buy the truck you want!
Exactly. I have a diesel but a gas motor is fine too. One thing about a diesel, if you trade every few years, a diesel is a bad investment. When I bought my diesel Ford in 1997, I planned on keeping it 10 years, it's turned into a bit more than 10 years....lol
