The 5.4 and the V10 share all the same internals basically, so who knows. The difference is the tranny - 4R100 or Torqshift, versus I think you have the 4R70W?
And the bigger platform is just nicer towing.

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.
Run the correct oil and filter and it will outlast every other part of the truck.
Like Art said, the way it handles with the weight and the transmission are what might be a problem.

My Expy has the 6-speed 6R75 mechatronic automatic transmission. It's been in once for a reflash and will be going back as it still flares between shifts. The 5 star tuning really woke up the truck and seems to shift better, but still flares. I also developed a passenger side exhaust manifold leak during the long trip which kinda lead me to believe I was pushing it a bit with the weight and length of our TT. I'm thinking a 3/4 ton truck will handle the TT much better and we may even step up to a 5'er next summer.

Diesel is dead.
15-18 mpgs don't make up for $.50-.80 more per gallon of fuel and the additional buy in cost (which now is even more than when new) and the maintenance involved (especially when purchasing used and over 200k on the clock).

OK jimmy, you've been hearing from the gasser advocates, so here's a diesel guys opinion.
For 23k I could buy an excellent diesel pickup, and it would have less than 100k. The amount of money you have to spend is not what will get you a good, or bad truck. Besides, from what you say you wanted to spend 10-12k on a truck. IMO you could get a nice early 2000s 7.3L for that money, and it will pull the load much better than your Expedition. I could go on and on about the pros of the diesel, but.... I've done that before.
And, for the record, gas and diesel are the same price all over southern Illinois.

For the guys that replied to me on the previous page my order went in to Ford Thursday. I went with the 4.30's. The new tranny has a very high sixth gear, .67. With that and the 18" tires over the 17's that came with my 05 V10 it only made sense. Also the higher torque curve on the new 6.2. Thanks.

This is incorrect, your wife's new F250 has 385 HP and 405 ft-lbs. 2011 Ford Super Duty | View Full Engine Specifications | Ford.com
So you have 60 horsepower LESS than her new 6.2L truck. Still 150 more ft-lbs though.

They must have the manual messed up. Either way they both produce the same peak HP and torque. For the 10,000lb and up trucks the performance figures are taken at a lower rpm for EPA purposes, I presume to pass them. Funny though as apparently they are the exact same engine with the same performance. I just went through this as I just finished doing an order for one. It is also discussed in the Ask Mike Harrison the lead 6.2 engineer thread.

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.

I'm not throwing rocks I'm just mentioning that alittle research and you can find an awsome truck that'll fit what you need. Be it a diesel or gas.

Anyway congrats on the new truck. I think you'll really like it. That rearend will sure make a differece. We,ve really been working our trucks the last 2 days. I went to Ark. And got a load of generators and she's been hauling lumber, water, food etc. She really seems to like it. Coming from a scab f150 you can really understand why.
