I also sincerely hope that you have a great day!
your post didn’t address anything about 3.73 trucks having worn out transmissions because the gearing isn’t good enough.

but thanks for wishing me a wonderful day I wish the same for you as well. We’re just debating trucks so I’m not sure why you’d think it was any deeper than that to begin with to where we need to clarify that we don’t mean each other any harm lol

One was Rapid Red with carpet and the other is Antimatter Blue with Vinyl floors. Other than that they were identical.

With the constant stop and starting of a landscaper pulling a trailer I would go with the 4.30 and never think twice.
If it's possible you're going to upsize the tires the 4.30 are even a better choice to put your final gearing in between the two on the highway.

A couple of days ago I picked up a new ATV and trailered it home on a 16 foot dual axle flat bed trailer. I'm guessing the trailer and ATV weighed 3,000 pounds. The truck shifted in and out of gears 8,9 and 10th running 65 on the interstate with minor hills. It reconfirmed I did the right thing by ordering the truck with 4:30's

between 1800-1900rpm at 70mph in 10th with 3.73s and 31.5" tires. About 2100rpm with 4.30s.

At 55-60mph with 3.73s in 10th gear my instant mileage readout stays around 20mpg. With 4.30s I have to be around 45mph to be at the same rpm and same mileage. With 4.30s it will shift into 10th gear by 36mph if you are just putting around and 3.73s will shift in 10th around 45mph. The worst thing about 4.30s with my truck is the 1-3 shift at 6mph. The worst part about it is that it tries to lunge forward once it shifts into 3rd. When I turn off advance trac or put it in tow/haul it will shift 1-2-3 and hold 1st and 2nd gear for longer. This isn't an issue on the newest trucks because they changed the shift strategy to not skip shift.

Took it out on the highway today. 7.3/4.30 Toyo M/T 295/70/18 34.5’s. At 65 mph it’s turning about 1800 rpm, at 70 it’s turning about 1900 rpm and about 1 less mpg.

Air dam is trimmed, it only hangs down 2 inches.

If MPG isn't a factor 4.30.

That’s some abysmal gas mileage for short highway samples

I think 16.1 mpg at 65 mph and 15.3 mpg at 70 mph is good considering it’s a 7.3 with 4.30’s, 34.5” mud tires at 50 psi front/45 psi rear, trimmed air dam at 5000 feet elevation. MPG isn’t something I’m concerned about.

I agree with Spratrat that 4:30 better take off torque if fuel mileage is not a concern

Don’t buy 4.30’s for driving empty at high speed. But why buy a truck to do that in the first place?
4.30’s shine at low speed or towing or both.

one of this forums biggest proponents of 4.30s or die tows a trailer that doesn’t even weigh 4000lbs. The question he should’ve considered is if he needed a maverick or a ranger lol.
Right here ^^^^^ no truer words ever spoken.
