Well I placed an order for a new truck today. I am going back to gas. Miss my old V10, I had the 7.3 back in MY96 and the 6.0 and now the 6.4. I hate the little problems with it and I keep wondering about outrageous repair bills down the road. That and dealing with them in the winter and regens. Finally decided I don't want to deal with the problems any more. I am getting a new 6.2. I only tow our 10,500lb fiver about 1000 miles or so a year and we are in mainly flat land with some rolling hills. I just need to decided between 3.73's and 4.30's before in gets built. The 4.30's would be nicer for towing, but that is such a small percentage of the time. I am thinking of the 3.73's as they seem to be getting about 1 mpg more with them overall. The 3.73's are rated for 12,200 or something like that. She'll be a bit slower in the hills but it should do the job.

Let 1st say that the new SDs are awsome. My wife finally moved from a 1/2 to 3/4 ton. She got the 6.2l cause she couldn't see the cost of another diesel. We got the 4:30 rearend and glad we did. While Ford was having her reseat removed and her tool box installed. That's right her toolbox is inside the cab. She is a LA vet. And she has a toolbox mounted in the cab. Ford let her drive another SD it had the 3:73 rears. Sure at certain times the 3:73 gets slight better milage. But in over all the 4:30s average better. I gotta say the 6.2 is a strong engine but really seems the 4:30 really brangs it out.

I can remember you from other threads from way back. What do you think your wife's getting for mpg highway with hers? What speed and what style is it cc 4x4? Why I was thinking the 3.73 would work is I had the old 4.6 and 5.4 and they pulled a 7500lb trailer with ease and they had 3.55's.
Thanks

I kind of rushed into this and don't have much time to decide. The order has to be firm by May 2 to take advantage of 7k in rebates on up here with Ford. The MY11 order bank closes on the 6th.

Your mileage won't siffer much with that small of a difference of ratio. If anything, the trans will thank you.
1K mi. year towing 10k?
Flat ground w/ rolling hills?
I would choose the taller gears.
I had the same senario.
My first Ford came with a manual trans and 4.10's. I was always looking for another gear, so I changed them out with 3.55's and found a real fun factor out of the combination based on the same topography. Yea, it was a little tall, but it was always running empty with a ton of diesel torque.
With your 3.73's you'll will be giving each gear more to work with. I think you'll also find there's more than 1 mpg to gain.
However, the change will put you to work when you start towing in mountain twisties.
But if you plan on ginormous tires, stay with the lower gears.
4:30 will take stress off the drive train. True the 4:30 will have "slightly" higher rpm at cruise speed. We're talking maybe 200 rpm. The 4:30 will actual get the truck moveing alittle smoothier. I was going to take pictures but we've been battleing storms all morning. Her truck is cc 4x4 larait. She drives 65-75 hwy avg 2000 rpm and we've hand figured 16.7-17.4 mpg. We haven't put a trailer on it yet. I don't put a trailer on a truck under 3k miles. Just me.
You should go test drive both gears. I promise you, you'll see a big difference. We where really disappointed in the 6.2s untell we drove one w/ the 4:30.
Mind you that these trucks has the 6.2l w/ 320 hp and 400 ftlp tq. Its the f450+ that has the 385 hp. Your twisting this engine up pretty good. The 6.0 does good w/ the 3.73s but that's 150 ft tq more and 15 more horsepower @ 1/2-1/3 the rpms.
Your 5.4 didn't get north of 15 mpg empty.

I am at this crossroad right now...which engine to go with. I recently purchased a travel trailer, ~7500lb loaded, and currently tow it with my '07 Expedition. I went to FL from MI a few weeks ago for our first trip with the new gear. The Expy did OK, but really struggled in the mountains through the NC-WV area. I averaged 9.5MPG for the 2700 mile trip. The wife drives the Expy and is looking to downsize to something smaller like a Volvo V60 or similar. This means I have to get a truck to do our hauling. I'm trying to stay around 10-12K. We are trying to get the Expy's value to cover as much as possible on the new vehicles. We owe nothing on the Expy and our local dealer said he would give us 23K as a trade. We just gotta find the vehicles now.
I also tow a 2 place snowmobile trailer, 2500lb, every other weekend all winter long, 20-30 trips typically. Most trips are 210 miles each way, but one or twice a season, I go to our spot that is 350 miles each way. The Expy was fine last winter with this, but I wouldn't mind having a truck again.
That's going to be a tough one... At 7500lbs, the V10 will handle it just fine, and if you get 4.30 gears, it'll be very happy pulling that.
But 9.5MPGs, well, you're probably going to be around the same, MAYBE slightly better, with the V10.
The diesel, of course, will do better on fuel, but will hit you in the pocket on the upfront costs. $23K would get you into a fully-loaded, slightly-used, V10. $23K might get you into an older diesel. It all depends on what your dealer can do for you.

Thanks for the quick response. I am concerned with the 5.4L over a prolonged time pulling that kind of weight and I get the impression that the V10 will not be stressed as the 5.4 was. I was quite happy with the MPG...I can't help but think the SCT tunes from Mike helped out considerably. Running the 87 perf/tow tune from 5 Star, I get over 20MPG on the HWY running 70MPH. I know the V10 won't touch that, but how much strain can I put on the 5.4 before she craps the bed? My wife and I are both teachers, so we utilize the summer to travel as often as possible. I drive 7 miles to work so I'm not really concerned about daily driving MPG. If I went diesel, my price range puts me back into the late 90's early 00's 7.3L...which is fine by me, I wouldn't get the 6.0L even if I could afford it.
