For what it is worth, I bought a Ford F-250, XLT 2019 model. In doing my research I found a huge price difference between the XLT and their top of the line model. A few options brings the XLT up to a very well equipped vehicle for a reasonable cost.
I found a 6.7 diesel with the suspension upgrades and nice trim options I wanted...and even preferred over the top of the line models. You can add the chrome upgrade option, trailer towing package, 4 door, bucket seats, large nav screen, and a number of other features and still be 20,000 under the top of the line models.
one thing to also consider by going to the 3/4 ton, is the heavy brakes, shocks, springs, transmission, axle, etc. that will give you years of added use over a 1/2 ton.
I have averaged 19 - 20 mpg without the Oliver and 14 - 15 mpg with the Oliver. Yes routine maintenance is higher for the diesel, but also is the resale. I could not be more pleased with my Ford F 250.
