3.21: 3rd (4118rpm) 4th (3275) 5th (2530) 6th (1961) 7th (1647) 8th (1314)
3.92: 3rd (5029rpm) 4th (3999) 5th (3089) 6th (2395) 7th (2012) 8th (1604)
With a big trailer 8th is out of the question for either truck.
If the 3.92 truck can pull it in 7th, by dropping to 6th, the 3.21 truck is at nearly the same rpm (2012 vs 1961).
If the 3.92 need 6th, the 3.21 can use 5th (2395 vs 2530). If the 3.92 need 5th, the 3.21 can use 4th (3089 vs 3275). And so forth.

I guess I could have been more clear. I do have multiple issues and I am trying to attack all of them on all fronts. The handling I am hoping is due to the tires, which we will see this weekend, and I am going to play around with the 4 point to see if I need to make some adjustments.
As for the gears, this was mainly to help me out with the inclines. California topography is very diverse. you cannot go 100 miles without hitting some major grades. This was an issue I noticed as many large toyhaulers were smoking me on the grades. And reading throught this forum, everyone seems real happy with their Ram 1500's using the 3.92 gears, while I am way down at 3.21. Not that I want to just piss away money, I just want to get my truck in as prime of towing condition as possible, so I can deal with it for another 3 years or so until i can upgrade.

Would you suggest a 3.92 upgrade from 3.21 with. $1000 price tag?

I pull my 28BHR with a 2013 Ram 1500 Big Horn Crew-cab 4x4, 5.7L, 3.92, 8 speed, Fastway e2 hitch, Air Lift 1000s. Pulled it all over Colorado and to California and back during the winter. I'm probably a couple hundred over the max payload but accept it. Tows well and the 8 speed with two/haul enabled keeps me relaxed on the up and down hills.
All that being said...I'm saving my money for a Ram 2500 with a Cummins diesel engine.

It's probably my skewed perspective because I own one ;), but the EB seems to be widely accepted as the current engine of choice for towing in a half ton.

I think I'd put the gear swap at the bottom of the list unless you tow the majority of the time or almost exclusively in the hills. As others have suggested there are some behaviors detailed that won't be impacted at all by that change. Fine tune your hitch/weight distribution and ensure you have adequate tongue weight. The LT tires you've upgraded to should definitely help. Also, make sure to use the Tow/Haul feature - it makes a big difference once you hang the trailer off the back. Bear in mind that you may need to lock out the overdrive when climbing longer hills with the gear selector on the steering wheel to avoid gear hunting.
