If you guys want resale value I have only one word. DIESEL!
I had a 2001 F350 crew cab 4x4 with the 7.3liter PSD. I paid 34,400 special ordered.
50,000 miles later with several dings and dents (i use my trucks), they gave me 28,000 trade in. Hell, I never washed the truck or cleaned the inside the whole time I had it until I traded.
Stepped into this truck for 35,500 and it will pull your house over.
