You're wasting your time with most of this bunch, they'll just never get something so simple........I tried a while back.

It took me a while to realize that you can lead a horse to water, but you can't make it think.

 

Ok your highness.

 

Whatever you say kid......now go away.

 

That's enough, play nice or don't play .

Yep! Totally agree.

 

"In a realm of preference, there is rarely a right answer"
A wise man once said this. The only way something like this will be solved is if Ford goes the way of the Tundra and only offers one rear end.

 

Tundra.., I was thinking GM HD 6.6L gas (3.73) was more direct comparison. 😆

 

Not to add fuel to the fire but, I see your reasoning on the gearing on race cars, but I come from a trucking background. Gear selection is decided on by optimum rpm for what mph you want to run under at the greatest load in direct (most efficient trans gear).
So figuring best gear is to calculate what rpm you want to run in 7th gear pulling at x mph up a hill. But hardly anyone who buys a truck really figures out the most efficient ratio
True most guys are fine with 3.73, but I say 90% of owners of 3/4 ton and bigger trucks don't need one, they want one. So any ratio will suit their needs.
My 7.3 has 4.88 and I'm plenty happy with the gear ratio, but I rarely drive over 65. Not most efficient on highway mileage but will pull.

 

As a VA resident I'm going to confirm this. Just got back from a 5 week trip towing our 34' 5'er loaded to around 11,000 lbs give or take with a 6.2 and 3.73's through Colorado, Utah, Wyoming, and back. We have some hills here on the east coast, but climbing those grades at 3k feet above sea level is not comparable to crawling up the "million dollar highway" in Colorado heading into Ouray, cresting Granite Pass in the Bighorn mountains, etc... 10k feet above sea level is a different ball game...

 

5 weeks sounds like a great road trip, hope you had a good time. Some great views on these western mountain climbs/ descents!

 

This was the only reason i ordered my 22' Was to get the 7.3 with 4.30's. I didnt want the Tremor. My truck to this day 7/20/21 has yet to be scheduled so I ended buying a 21' new off the trailer but with the 3.55. It was there and i could get it now and it was exactly what I ordered minus the gear. My trailers are all under 10k so it was not a big deal. If I feel I want that lower gear I can always just install 4.30's.

 

I agree, I live in Eastern Pennsylvania and we have some of the sharpest turns with steep grades I've seen, I've driven through the rockies and they have longer inclines I.E Hills that take a couple miles to climb, we have VERY steep hills, not very fun sometimes

Edit: I know altitude makes it different in regards to power etc., but I don't really care how fast I climb I hill, it's how SLOW I go down the other side, and when you climbed a hill with 12% grade, and have to go down the other side...

 

going to Twin Grove Campground, there is 3 mile section of 501, if i remember right, thats 9% grade both up and down and it twists and turns. Its fun especially this year cause we were on it in a down pour and couldnt see more then 30-50 ft in front of the truck.

 

Once you get a chance to do some towing, report back how your new rig is working out. I think you are going to be pleasantly surprised. My 2020(sold) with the 7.3L/3.55 handled a 7,500# travel trailer at 9,000ft elevation easily and pulled my 10,000# skid steer effortlessly. Also cruising unloaded at highway speeds at 1500rpm is a pleasure. I hope it does everything you want it to. If not, hopefully you have not cancelled your order and can sell your '21 once your 22 is built.

 

For the SD owners that install larger tires.




The 285 75 18 is the size used on the Tremor and 35” that is a common up size.
