Re: Buying new truck: ? about gears and cab configuration
Sheldon Cooper wrote: Looking for input I will tow a 33'5th Wheel with a UVW 9,195 & Hitch Weight 1,695 My truck to be is a 2017 F-350 diesel single wheel 4x4 short box. I will not have passengers. My questions: 1. Pluses and minuses of 3.31 or 3.55 gears for towing this 5th Wheel. 2. Which cab configuration? Crew Cab = 160" wheel base Super (Extended) Cab = 148" wheel base 2a. Does the cab style affect driver comfort, handling, or fatigue while pulling? I.E. Am I going to be white knuckling the steering wheel with one or the other? 2b. Does the wheel base affect driver comfort, handling, or fatigue while daily driving and not towing? 2c. What about backing pluses and minuses with each cab? Does one have an advantage over the other? 3. Does selecting a different GVWR package make any difference for towing? I.E. There is an option for 10,000/9,900 and 11,400 GVWR package. 3a. Why select a higher GVMR? With the ford 6.7 diesel SRW,the differences in gearing is mad eup with the tire choice. 3.31 - 20" tires 3.55 - 18" tires431Views0likes0CommentsRe: How often do you cange oil if little us
I would recommend changing the oil at least every 6 months at the latest. I know that most OEM say do it at least once a year if it doesn't meet the milage but to me it's cheap insurance. Also I would recommend 3,000 mile changes if it just going to be used for towing.85Views0likes0CommentsRe: Advice needed on new truck
1) For reliability from the big three I would say they're all pretty much equal. 2) For gas vs. diesel it mostly depends on personal preference, a diesel will pull a bit better and get better mileage while towing then a comparable gasser. But a gasser will pull whatever it is rated for but at a higher RPM to keep it in its powerband. 3) It used to be true that diesels would get much better MPG then the gassers of that year, but with the new emission equipment on diesels that gap has narrowed to maybe 1-4 MPG stock-for-stock 4) I have no experience around CNG trucks but would imagine that it would be very similar to towing with a gas engine. The worry I would have with that is finding fuel stations that stock it as I know of only one around the area I live that sells it.102Views0likes0CommentsRe: You choose - loaded gas or basic diesel?

I'm not sure how that HP=Torque X RPM/5252 came into play,but I personally have never seen it come true for any engine Take the 6.2L GM engine with 420HP @5600RPM 460 Torque @4100RPM Following that formula it would be as following HP=(460*4100)/5252 Which equals 359.101 The formula is just a general guideline. There are mass, friction, and combustion issues that enter into the overall design of an engine that are not reflected in this formula. FWIW, I could be mistaken, but I believe this formula calculates the torque being produced at the same RPM when maximum HP is being produced. Using the numbers you provided (and this formula), 394 ft. lbs. of torque are being produced at the same time 420 HP is being produced at 5600 RPM. The general point I'm trying to make (with this formula) is that there is a give and take in terms of HP, Torque, and RPM. Some seem to think that HP is the cat's meow all by itself--that an engine with tons of HP will some how perform better under all conditions without any regard to its torque characteristics--that is simply not true. Again, HP is the product of Torque and RPM. Change one variable, and the other one or two variables must change, too. Thank you for explaining that. But thankfully with the way the engines have been able to produce their power its getting closer to the point where people can have their cake and eat it too.343Views0likes0CommentsRe: You choose - loaded gas or basic diesel?
