Are there any here who have the 6.2 gas in a 350 Super Duty and how are the real numbers for mileage and power. I realize the diesel is going to have a lot more power however the price different is about $10,000 and the cost to service, repair will be less as well.
Maybe my experience can help you.
I started with an F-150, 5.4 V8. My tt loaded weighs approx 8,600 lbs, but it has a heavy tongue weight of 938 lbs dry. The 5.4 V8 handled the weight of tt okay, but it didn't handle the tongue weight very well.
So I bought a F-250 with a 5.4 V8. Bad decision. While the F-250's suspension and long wheel base handled the tt very well, the truck being much heavier than the F-150 took a toll on the 5.4 V8.
The F-150 was a single cab short bed (4 doors with the extra storage room behind the seat) and the F-250 was a long bed crew cab. So it was a much larger truck.
So a few years later I found a good deal on a F-250 with a V10. This truck worked very well with my tt, but man that V10 was really thirsty loaded and unloaded. Being a gasser, it still screamed going up these hills in eastern Oklahoma.
This past July I purchased a used 2012 F-250 with the 6.7L diesel. I have made one trip towing the tt. 90% of the trip was on a winding, hilly 2 lane road. All I can say is I love this truck! The truck took the hills easily, some fairly steep and a few long climbs. MPG are much better than the V10, loaded and unloaded.
I also had read the comments of others about the difference in towing with a diesel vs a gasser. I believed everyone, but I never realized just how much a difference that would be until I towed my own trailer and experienced it myself.
Now whether a diesel is worth the cost difference......you'll have to make that decision yourself. We all tow different campers in different terrains so we all have different towing experiences.
Hopefully this has helped you somewhat. Good luck and keep us posted on what you decide.
