Having recently got my first F250 ( 97 HD) I would like to hear from those of you more experienced, on the feeling of towing the bigger AS ( 25- 34') with our rig. I was next to a guy in a new F250 pulling a Cigarette boat that looked as long as my trailer- 31'....and we seemd to both accelerate from a stoplight at about the same pace. Just trying to determine what power you all feel seems right.
Cruising at 50 the RPMS on the diesel are pretty low even with the AS behind me. But I have nothing to compare it to.

Alan, I can't help you with the engine and rpm's in your truck; however, I have a 6.0L and six speed transmission in mine and in tow/haul I don't get into the final gear until I reach about 62-63 mph. This puts my rpm's towing about the same at 75 as they are at 55. This is pulling a 30' Safari which proabably compares in weight to your 31'. My Safari weighs about 7,100# empty and dry, IIRC. Loaded for a week end of camping, who knows? :LOL: Under these conditions I average 12.8 mpg's consistantly on mountainous interstates. (I don't tow anywhere near that fast off of interstates!)

I know this doesn't help with your model of truck, but it will help confirm that diesels have plenty of torque in the lower rpm's and tow smoothly without having to keep the pedal to the floor.

recent experience

'05 F250 CC PSD towing my 30' Safari this past weekend. 4 adults one child lots of stuff no idea how much it all weighs (but I know it is well within spec)... towed about 800 miles in very mountainous terrain. And did 50 plus miles off road in 4X4 (not while towing ) and another 100 miles exploring the back country of Monument Valley...11.8 MPG for the total of 950miles... While towing on the interstate at 70mph the RPMs sit at about 1800-1900 and you have plenty of power in reserve to climb big hills or when you encounter a slower moving vehicle plenty of power to safely pass. Also note coming thru Flagstaff, AZ on the way home I encountered the strongest winds I've towed in to date.. Easily 50-60mph gusts. Never once felt like I was not 100% in control of my rig she is very steady can't even imagine towing in these conditions with anything less than a 3/4 ton chassis.

I have a 1996 F-250 Powerstroke, Ext Cab Long bed with a Camper shell. I get right at 18mpg with mixed around town driving and about 16 towing.

My fuel mileage really goes down if I am running at 75 on the interstate.

Alan,
Part of it will depend on which rear end ratio your truck has. It will more than likely be either a 3.73 or 4.10. Mine has 4.10's. At 65 mph I am taching around 2250 rpm. 55mph is the sweet spot for my truck in terms of power vs economy. At a constant 75mph I only get about 13 mpg. At 55 mph I get close to 18mpg. Normal unloaded on the interstate running right around 65 mph I am getting 17 or so. I am also running an additive due to the lowered sulphur content. I don't know if that makes a difference or not. But with a replacement engine in the $5-8k range I don't want to take chances. BTW mine is a 1996 F350 CC, Dually long bed.

I was running b100 bio when I towed last week. Not that it made any difference other than the smell.

Where do you get your b100? I haven't seen any stations advertising it on my side of town. Looks like there probably isn't any performance difference. What kind of smell did you get? Mine doesn't smell too much when idling.

I bought it at S A White
oil in Marietta, check out the atlantabiofuels web site too.
I paid 2.70 but its down to 2.35 for B100 or less for B20.
It smells like grandma is frying alot of chicken in the kitchen, as its made from local chicken fat.
In fact I walked past a restaurant in a parking lot and thought my truck was still running.
Supposedly it will clean out your system and you might have to change the fuel filter, at least after the first few tankfuls.

Well it is time for a fuel filter change anyway. My dealer (consider the source maybe) recommends changing the fuel filter every 20,000 miles. Does that sound right to everyone else? This is my daily driver and I am just over 20K miles.

Sounds right to me. I usually maintain my truck by the book. I do oil at every 5k, change fuel filter every 4 changes, unless it gets contaiminated prior to that. Add a bottle of additive to the cooling system every 30k and that about covers it. Rear end gets oil changed once a year whether it needs it or not. Don't recall on the tranny but it is getting close to time to do it again

Ford says a new fuel filter every 15,000 miles.

Well, my regular shop hasn't recommended one yet, but I plan on taking it to my Ford dealer for the next oil change...found out they are about $50 cheaper for the filter and oil change!

How much is the fuel filter? I forgot what the dealer quoted, but it seemed tremendously high, like maybe $100 or more.

They ain't cheap. I buy mine at Napa and IIRC they are around $45-50. I know that the NAPA Gold Oil filters are right at $20 for the oil filters. I buy oil by the 55 gallon drum around here. We get Rotella for around $3 a gallon that way. But I am sure it has gone up since the last time we bought any. Sam's Club sells the gallons by the case.

Hi, overlander63. Ford medium duty trucks were F-650 & F-750s. The F-450 & F-550s are a relatively new creation. These came out when or after Ford sold it's larger trucks to Sterling.
