RE: just a little more power
Not anymore. Most HD pickup trucks only have one gear option these days.
Not for gas trucks. Dodge offers 2 options, Ford offers 3. Gm is the only one that does not have an option. They haven't for a while iirc.
There are only 3 major manufactures of consumer HD trucks, and 2 of those offer different gear options, with increased tow ratings for deeper gears, for the gas trucks.

RE: just a little more power
I'm not sure why people think the rear gear ratio only changes rpm/mph.
It increases torque multiplication to the rear wheels. It will tow more easily in all gears. It may allow towing one gear higher than usual
If the truck is in fact a 3.73 truck, it will make a difference going to 4.30's. Ford didn't offer that option for fun.
Yes, it will increase cruise RPM in 6th by 2-300 rpm. Might loose 1mpg unloaded. But as Fish stated you may gain mpg towing.
You know WHY it "tow more easily in all gears?"
Because the engine is running at a higher RPM at all speeds!
The engine produces more HP at higher RPMs, up to the peak of the power curve.
People think "gear ratio only changes rpm/mph" because that is precisely what it does.
If you were doing 60MPH at 2000RPM with stock 3.73 gears, you will need to rev the engine to 2305RPM to maintain 60MPH with 4.30 gears, or you will only be doing 52MPH at 2000RPM.
You still have torque multiplication happening.
For easy math, lets say you have an engine with a nice flat torque curve.
100ft lbs at both 2000 and 2300rpm.
Running in direct (1:1), also to make the math easier.
100ft lbs x 1 x 3.73 = 373 ft lbs
100 ft lbs x 1 x 4.30 = 430 ft lbs
The main benefit is not that it puts you at a different rpm closer to the torque peak...it is that you increase the torque multiplication in every gear.

RE: F150 Lightning Road Trip & Ike Gauntlet Pull
Well this certainly descended into a pissing match of total silliness lol. Thanks for the laughs.
Right?
It towed the trailer very well.
Are there range issues. Yes
Is anyone surprised by that. No
Can you make it work if you change your driving habits. Probably
Does it have impressive power and is unaffected by elevation. Yes
No one is surprised by that either.
It did a great job towing the IKE and didn't break down on the road trip. But it's not for everyone.
No big surprise there. ICE vehicles will be around for a while yet for heavy work.

RE: Travel Trailer Towing Recommendations
OP did say "seat as many grandchildren as possible"...not that he NEEDED to fit all 10 kids all the time.
Also, they haven't chimed in since page 2. :)
