If your truck is new crawl under it and there is a sticker on the axel with the ratio.

Oh boy……now you did it

Easy enough.

Get on the highway and go 70 mph. If the pistons fly out of the block and valves dance on the hood it's a 3.92. If you keep your testicles in your wife's purse you have a 3.21

To be clear.
I have 3.92s but I knew that when I ordered it.
In hindsight probably should of done 3.21s for the way I drive but oh well.

I have 3.92 rear end and am glad I do. the truck has plenty get up and go and it is a great gear for towing. at 70 I think the rpms are around 1900 and when not towing I nearly always get 20 mpg if I stay under 80.

That's great.
At 70mph I get around 17mpg on 100% flat ground.
My RPMs are in the 2k range already at 70mph
74mph is around 2400 rpm.

Edit: I'm at 2200 RPM at 74mph with 3.92s. I don't have a lot of flat ground in my part of the country.

sounds like you are running some lower gears.
