I will post later what they find out is wrong with my truck otherwise the trip to Havasu was fun in the sun but it turned tragic sunday on the way home.
Sorry to see you had bad luck, I bought a new 2008 hoping not to have a breakdown & delay while traveling. Happened to me last year, it is the pits.
We just got back from 1665.1 miles towing 16,650# Could have not been happier. Have a further report on another post.
Fuel mileage: 190.83 gallons for 1665 miles all towing, the computer showed 9.1 and hand calculated 8.73. Usually drove up to 5 mph over the speed limit under 60 and tried not to exceed much over 65, except in W. VA where it was 70 mph and kept it lower than the speed limit on some really rough roads and bridges. It also surprised me coming off traffic lights in heavy traffic, ¾ throttle had to look behind me to be sure the camper was still there (well almost) it really pulled strong and had no problem staying with traffic between lights. If you want fuel mileage go with a 250 standard cab with 3.73’s, If you are going to tow heavy go with either the 350 4.10s, 4.30s if heavy or a 450. From what I have experienced the 4.30’s will have no problem even over 20,000# towing. I wouldn’t think you would need 4.88’s unless you are towing 22,000# plus.

If you were to read the 7.3 forums, and you base it's reliabilty on how many problems people post, you would think that engine is a problem prone POS. For some that may be true, but overall the 7.3 is considered to be one of the most reliable engines out there.
NS F250,

I understand that people that have problems tend to post on these forums more then those that don't. I'm not saying the 6.4 is not a good engine. It is too early for me to tell at this point. It looks like the 6.4 being the first year is having fewer problems then the 6.0, but it is the towing fuel mileage that is bothering me. I have to make a decision on whether I want to spend 120K on a diesel truck/33-35ft 5th wheel combo or if I want to spend 85-90K on a 35ft gas motor home. I don't see any difference in fuel mileage in the 6.4 towing vs. the gas engine motor home from what I am reading. I understand that the diesel has more power and that they last longer and right now diesel is cheaper the gas. I just have to decide if spending another 30-35K for the truck/trailer combo is worth it. That is why I am trying to learn everything I can before I have to make my decision. I appreciate everyone that posts their experience on here. It helps others to be able to make an informed decision.

WolfFox good points you brought up. So many other factors other than fuel milage. Do research on say 4-5 years down the road, resale value on both. If you are going to be driving a lot of miles with the RV like over 5,000 to 10,000 miles then a Motor Home might be the best. But if you are like me about 2,000 to 3,000 miles a year a Fiver might be better. It is also easier to trade up in a few years just the Fiver as far as depreciation. This way your Truck does not sit and you can use it during the year. My 99 F350 depreciated $19,000 in 8 years thats $2375 per year. Our Fiver depreciated $13,000 in 6 years thats $2166 per year. I trade my 99 for the 2008 this year and will trade to a bigger Fiver next. Over 5 years a Motor Home might cost you $30,000 more in depreciation to own. Hoping to retire in about 8 years and purchase a Motor Home then. See my other post on 6.4 towing 16,650# in 16650.1 miles.

I was refering to your comment about Ford not getting it right. Over all it seems to me that this engine is performing well for most. Well, maybe not the fuel economy, but the numbers do seem to be coming up. The good thing is you have 2 two years to wait and see what happens. The only problem is, Ford will have to add more emision stuff or redesign thier diesel engine all together for the 2010 emisions rules. So, back to square one. I too am watching these threads to what happens. I won't be in the market till next year, especially if the rumors about the 6 speed auto are true. By the way, check out the dodge forums, that 6.7 seems to be having more than it's fair share of problems.

broken 2008 ford f250

I will get my truck back on tuesday it has been at the shop for 2 weeks the problem was the fuel pump and i think the cost of the pump and all the bolts was 2200.00 all the bolts have to be replaced you can not use any old bolts once openned plus I believe 2000.00 in labor the cab has to be removed for them to get to the fuel pump everything will be done under waranty and they did pay for the towing back to san diego which was 1800.00 total 900.00 for the fifthwheel and 900.00 for the truck but our vacation which was suppose to start this last monday is delayed right now until we get the truck back I talked to them today everything is back on the truck but they said they need to run some more test on monday per ford engineer then they will give me the truck either monday night or tuesday they said.

The emision changes are nothing new. With the EPA taken more actions towards diesel powered vechicles, these changes will soon becomes as frequent as the gas industry. People waiting to find out what happens with these new emision standards will find themselfs on a never ending journey as times change.

All we can hope for is better results in time with new emision regs and advancements in tecknowledge. Just my .02

Pretty good news that it will be back, Still a drag what you went through. Did you have the extended warranty to get the towing of both back? I'm really surprised they covered both for your. That is really great considering. Best of luck when you get it back and have a great vacation.

I'm slowly getting better MPG myself. When I got the vehicle new at the dealer, I was getting 8/mpg. After 3 weeks and 800ish miles, I'm at 12.6/mpg. And everyday that average is increasing.

yes I did buy the extended waranty for 100k miles bumper to bumper with no deductible and they also told me that if you do not have extended waranty you do not even get a rental, not that i need one but it is there if need be the ford dealer did come true but it is delayed and changed our vacation plans.
The word is that they are not having any issues with this truck but the fuel pumps on them and aparently this is sourced directly from ford engieners to the mecanic that actually did the work on my truck. now keep in mind I already have 10k+ miles on my truck and this is just towing my fifthwheel to places with the family.
the way I look at it is they have to work hard to make me happy because ford is not selling 30k to 40k trucks out there and when someone walks in to your dealership and spends 60k+ on these new trucks they should get a diferrent level of service.
that is the same reason you go to xyz restaurant for a hamburger at 10.00 dollars or go to macdonalds for 2.00 dollars nothing against macdonalds just giving an exemple of what we should expect when we spend our hard earned money.

No problems as of yet with 2K miles on her. The 250 is getting 12.1 going back and fourth from work with the A/C on all the time. Towed my enclosed three bike trailer last week 1100 miles round trip and saw a steady 11.2 at 80 MPH.

believe it or not when towing the 250 is getting better MPG then my 06 F150, the 150 at 80 MPH saw a steady 9.2 while towing the same configuration. Saw in the city 12.4, so when I factor in the cost that Diesel here is usualy .10 cents cheaper then regular, it all still works out for me, I'm getting a tad bit better MPG then before and saving on avaerage 10 cents per gallon.

You'll probably get that nervous feeling going through Barstow on the way home.
