Towing with the ford 250 6.2 gas engine

I HAVE A 2017 MONTANA HIGH COUNTRY 293RK, 10,000 LB DRY WEIGHT. I TOW WITH THE 6.2 GAS AND 373 GEAR. IS THERE ANYONE OUT THERE TOWING WITH THE 6.2 GAS AND THE 430 GEARS. WHAT WOULD BE THE DIFFERENCE IN GAS MILAGE BETWEEN THE TWO GEAR RATIOS, AND TOWING ABILITY. GLENN

I doubt you will find to many people towing with that low of gear even though you would certainly have more power. There is a lot of difference between 373 and 430 gears. Most would have 410 gears or higher like what you have. The 410's would certainly lower your mileage probably 2 or 3 miles to the gallon. There is no substitute for diesel's but if you have a late model truck then you might be better off keeping it. Just remember if you have an 4 wheel drive then you have to change both front and rear gears which might be cost ineffective.

The 4:30 gears would kill your gas mileage.With the 6.2 you should have plenty of grunt to tow that unit.

What the truck will get for mileage is dependant upon year, configuration of cab, length of bed as well. Being gas is not a good starter. I really doubt that your truck can meet its towing limits and rear axle limits even with a high country that will weight more than any stated empty weight by keystone. Verify weight as you have it loaded for travel and I bet you are north of 14,000 lbs and 2500 lbs of pin weight. You have it, but is it really usable for towing a big fiver...

I have a Ford powered motor home. It has 430s or lower gears. With your 6 speed transmission the top two gears are overdrive. You will be just fine with that truck. I’m sure some people here would have you pulling your camper with a Peterbuilt. Try your truck before you trade it on a tractor trailer.

You will be fine 90% of the time with 3:73’s and the 6.2. Only time you will notice it is on long steep grades of 7% or more and it will pull them just fine, the 6.2 will just be wound up a little tighter than usual. A good friend drags around a 18k pound excavator with a 6.2 and it’s lasted over 250k miles and he has 3.73’s. His mpg loaded hovers between 6-7. Be careful as Lynwood implied most think you need nothing short of a F450 or Kodak to pull these 5ers. 4:30’s would kill any mileage and be overkill.

Hook it up and drive it for awhile.Check the weight specs. We first pulled our 06 3400 with a 2005 F-350 V-10. Our first long trip was about 7K miles all over the country. When we returned we traded for a 2008 F-350 6.4 Diesel . It is nearing 100K miles .

If you tow on the east coast yes you have hills. Ok just to keep the blowback down I am from Andover, Mass, but if you tow on the wast coast we have Mountains here and a gasser will have it's problems. You need the torque the diesel has.

For the life of me I just can't understand people. Beleave me I am the same. Spend $50,000.00 plus for a fifth wheel and not buy the proper truck to do the job. Or buy a 2X4 instead of a 4X4 when the 4X4 cost a bit more and only gets 1 MPG less. Yes, yes you can tell me you never have needed a 4X4 (I only stay in RV parks) BULL I have been in several RV parks that in the early morning when the grass is wet a 4X2 would not have gotten me out off. Or how about, let's see the rig was $60,000.00 and the truck was $70,000.00 and where's a Walmart parking lot I can stay in for free? Again don't get me wrong I have done the same thing. I look back and think what was I thinking about.

Just saying is all.

The problem with 4.30 gears is what about when you are not towing? That is way to much gearing for anybody. When they build your truck they match the gears in the transmission to the drive gears. Changing them will only mess up the ratios and may damage the transmission. Not to mention the higher RPM's at highway speeds. Just stick with what you have. I have the diesel with 3.31's and it does just fine. I see no reason to change them to 3.73's

The factory is not going to put a gear ratio that is going to damage the transmission.
The only time 3.73 is better is when you drive at highway speeds.Ive been towing and just driving to work with my 2011 and now 2017.Works great.If I was to get a heavier camper over 1200lbs empty, I would get a diesel. But the 6.2 does great for what I use it for , that is why I bought another one (2017).
