Coming from a under powered 5.8L gas truck, I was not convinced that the modern 6.2L gas trucks would perform all that much better than what I already had. As an example with the camper on I had ~200-225 mile range with 34 gallons of gas.
As it ended up the decision came down to special order a truck or buy the last one off the lot. Around my area, all the dealers lots were chock full of Crew cab short bed trucks, but it was a challenge to actually find a super cab truck with a long bed. Since I was already leaning diesel it was a no brainer that the last super cab Ford in my area was a 6.7L PSD.
Personally, I like the power and fuel economy.
