70 MPH - 7.5 mpg
67 MPH - 9.0 mpg
60 MPG - 12.5 mpg

The speed was tested for a minimum of 50 miles for stabilization. Not very appetizing or admirable for FOMOCO. There really needs to be a diesel option in the 150.

Sorry to get a bit off topic, but you reminded me of a conversation I had the other day. The guy had just recently bought a new 08 Super Duty with the 6.4 liter diesel. It developed a leakage problem which was caused by a faulty o-ring in the area of the oil pump. Luckily it was fixed on warranty as the job takes 28 HOURS!!! In other words a couple bucks for the o-ring and $2500 to $3000 in labor to replace it.

What you probably meant to say is that the F150 needs a proven and reliable (and preferably simple) diesel engine. A diesel mechanic told me a long time ago that diesels ought to be in-line 6's and a 5 litre in-line 6 would be a great motor for the 150.

Simple answer. NO!!

With 6 people and a loaded bed you are probably at or over the GVWR which should never be exceeded. In other words, you can probably safely tow nothing. Fords towing trucks are the F250 and F350.

Oops, just noticed those two little letters "hd". I should have said Fords towing trucks are the F250 and F350 and the F150 with the HD package. Congratulations on finding an HD truck and having the sense to buy it. They are really hard to come by here in Canada. The local dealer where I bought my truck has pretty well given up trying to get them and they sell a lot of trucks.

When I visited the other dealer in the city they were quite adamant that Ford doesn't make an HD F150.

The reason that I have maintained an interest in the HD package trucks is that the first new series F150 I ever saw was a Scab HD. It was in Flin
Flon, Manitoba and I still wish that I had bought it. As they say, "too soon old and too late shmart"



i was looking at my manual and found that the total combind weight or GCWR of my truck should not exceed 15300 lbs. so truck payload and trailer should not exceed that. I orginaly bought the 150 with the hd package only because i wanted a 5.4 with the long bed. but when i saw that they had the x-cab for 3k more i thought it was a no brainer. The xtra room 410 gears and d range tires for only 3k more.

Go to the scales and weigh your truck full tank/people/gear/wood/etc.. (anything in truck while towing).

Hopefully that number does not exceed GVWR minus (500-800lbs tongue weight).
Take that number and subtract from GCWR and you have max trailer weight.
Tongue weight needs to be added to truck loaded weight to see that it does not exceed GVWR. tongue usually 10%-15% of trailer weight.

In most instances it's the GVWR that is exceeded before any other number.

Thank you for helping to bring a sense of reason into this discussion. That has been my point all along. The only number that really counts when it comes to towing legally, and thereby safely, is the GVWR as stated on a sticker on the vehicle. If you are over that number FOR ANY REASON you are beyond the legal and safe towing limit.

You are getting mixed up between load capacity and Gross Weight Rating. When you talk about truck payload and trailer weight you are referring to load capacity and towing capacity. When you are talking about Gross Combined Weight Rating you must also include the weight of the vehicle, ie. vehicle curb weight plus the weight of all the fluids required for the truck to operate. In your example the TRUCK WEIGHT plus truck payload plus trailer weight including trailer payload ( a tank of water can be quite heavy) should not exceed 15 300 pounds.

The other, and maybe most important, feature you get with an HD package is a GVWR of 8200 pounds which is 1000 pounds more than the closest F150 model.

Ford will use that GCWR figure in their advertising just as will all the other vehicle manufacturers with a small print disclaimer which states "with truck properly equipped". In the case of the F150 that simply translates into "with the HD package".
