hi guys! new user. i currently have a 2006 f350 6.0 diesel cc fx4 4x4 dually. truck has 330,000 miles with original drive train.everything working fine buy the way. thinking of buying 2013 f350 reg or super cab with 6.2 gas. been looking at mileage posts on here. my 6.0 has 4.30 gears it gets 14 @ 70 empty and 10 to 11 towing, 6000 to 10,000 lbs. i own an rv transport business so i tow pretty much every day. it's time for a new truck diesel is a lot $ to maintain. i knw i'll loose some of towing power on hills but new diesels are 60k. any thoughts? any one else go from diesel to gas ???

 

IMHO...in your line of business...I'd stick with a diesel. The 6.7L is really a GREAT engine...and your fuel mileage will increase some.

If you are serious...then I recommend jumping on a 2012 6.7L with all the discounts and rebates offered. That will save you a ton of cash...

As much as I like my 2012 6.2L...I would not tow heavy with it every day. The fuel mileage would eat the profit line.

Just my .02 here...

Good luck either way...

I use a V10 in the same line of work, and am having trouble deciding if another gas truck or a diesel will be next, MPg numbers for you, Lowest ive see was 6.3 and the highest was 8.1. Depending on the weather.

 

For what you use it for I would go Diesiel. Love my v10 and my 6.2 but I only tow 8 to 9k.

 

oneaddicted: I would tend to agree with what others have said. Given your line of work, a diesel probably makes most sense for you in the long term.

But, if I may ask...
1) Where are you located? Are you usually/typically pulling over mountains?
2) What is the typical size of the RV you transport? Are most the big, 35'+ 5ers?
3) What are the typical differences in gas vs. diesel prices where you reside?
4) I would imagine at 330k miles, your 6.0 is getting somewhat tired. Have you considered swapping in a newer 6.0 power plant? Or is the rest of the truck just as tired?

By the way, I went from a diesel to gasser myself in the past few months (to a V10). But I don't tow nearly as often as you.

 

The 6.2L would tow just fine, Might use a little more fuel than diesel.. 2 more mpg maybe but it would do the job. my 2 cents.. OR you could wait for the SD to get the 5.0L EB motor thats rumored to be 14-15 model. Again rumor is..

 

i'll be calling you about tunning one, i have some ? thanks for in put

 

i live in lower desert in calif. sometimes tow big ones, but mostly 6-10000 lbs. know a guy with a dodge 5.7 3500 flatbed 6spd man he does same thing. gets worse mpg towing but better coming home empty. if it got 15-16 empty i'd be the same. but up keep is less. yes 6.0 getting tired, not super bad but worn none the less. huge $ to fix though. just lookin at other idea's. the guy with gas 3500 came from cummins with 440,000 says he'll never go back. very little problems, no so with diesel and i maintenance mine religiously.still issues.

 

I would stick with a diesel. It was quite a shock for me to go to the 6.2 gas after driving my 6.4 with H&S Tuner with 400 plus HP. On the other hand, if you put a 5 Star Tuner on it with 4.30 gears........that set up I believe would work!

 

6.2 would do just fine.

I think the others are missing a very important component to deliver work. Rig down time means no money coming in.

A $5,000.00 diesel repair could be 1-3 weeks of down time. Suddenly that $5,000.00 repair really cost 7-15k with the down time. (down time = no work)

IMHO.. we will start to see an increase in gassers in this line of work. There are many fleets who are going with gassers to replace diesels... I wonder why?

The 6.2 gasser would be a very wise decision OP.

 

I've also noticed in my area that more and more of the works trucks are gas these days. Even starting to see some of the Eco-Boost F150's as work trucks.
I currently have an old 96 dodge diesel that we mainly just use for truck duties and camper pulling. I'm thinking we may switch to gas next time since the truck as so much cheaper and we don't drive it much anyway.

 

I went from a:
2003 7.3L PSD
2WD CC 6.5 ft. bed

to a:
2011 6.2L 3.73 rear end
4WD CC 6.5ft bed

and I love it. I still hear it almost daily for letting the diesel go but it was time. I do not use my truck near as hard as you do pulling trailers every day. With that in mind I pull a 27 ft. toy hauler. This toy hauler has steel in it. It was made with strength as the first priority, and weight as an after thought by Kit manufacturing. Empty, I put it on the scales and it was 8700 lbs. If I load it with my four wheelers and camping material I am ~ 10,750. My 7.3 would get 8 MPG towing 65-70MPH. My 6.2L gets........ 8MPG towing 65-70MPH. NOw as far as performance, the 6.2L obviously won't run in 6th gear uphill and maintain speed but I lock 6th out and have it in tow/haul mode and tow with no problem.

Towing 10,000 pounds in the 6.2 in 5th gear between 65-70 I'm running high 2000RPM. If it kicks down to 4th gear it's still only about (I say about because I did not take pictures, it was a mental note) 3250 RPM. NO where near the 5000+ redline and it never has a problem.

NOw a key disclaimer, I live in Kansas so hills are low and long so nothing steep. Just my experience in my truck. Towing everyday across country could be different, but for what its worth this is my story.

 

I went from an 06 with a 6.0 to a 12 F350 with the 6.2. The diesel has more power and will get better mileage but it is kinda nice not to have my truck in the shop for a few weeks a year! I get 5-6 mpg while pulling our skid steer trailers and 10-11mpg empty, but gas is cheaper than diesel fuel and the 6.2 hasn't been in the shop yet with 43000 miles on it. You will be fine with the swap you just have to realize the 6.2 won't pull loads as easily as the Diesel engines but it will get you where you need to go. I have also pulled our mini-excavator quite a bit the engine will pull the trailer as fast as you want to go it just works a little harder. I think that trailer is close to 16000lbs, the tag on the mini-ex says it weighs just over 13000 lbs and the trailer is around 3000lbs.

 

I very good point indeed. This is why my company fleet went to all v10 trucks for class 5 and lower. Not only were the repair bills terribly expensive on the diesel trucks, but when they were in the shop they still had to pay us. So far on mine after 2 years and 45,000 miles it has been in the shop once, and this was for a bad computer.

 

oneaddicted you may also look at the F450 with a V10 but you will have to put a bed on it. I,m looking at going that way maybe in late spring but I'm also still looking at the 6.2.
