How much can my Titan really tow?

So I just bought a 2012 Titan SV 4x4 from a shady looking individual. I've been thinking of taking my Dads travel trailer off his hands. Total loaded weight of this bad boy is a hair under 8000 pounds. Only problem is I can't seem to find my gear ratio or towing capacity. 3 dealer phone calls later and 3 different answers ranging from 7000-9300 pounds has me scratching my head. So I thought I'd come on here and see if someone could help me out. Here's what I know...

2012 Titan SV 4x4
Has Trans temp gauge, but no Big Tow mirrors
Has Front tow hooks, receiver hitch, and rudimentary brake controller installed, all look to be factory OEM (but I'll admit I've always been a Chevy guy and I feel the only thing the previous owner ever hauled was his *** down to the meth store, so i don't see him installing these for any reason).

I've looked for the sticker on the rear axle and it seems to be long gone, I've tried doing 70 down the highway but I'm at 1800-1900 rpm just in between what everyone on here says is the difference between the 3.36 and 2.93

This might be a stupid question, but when my families safety is involved you can never be too careful. Thanks in advance.

You're confusing GVWR for the truck (Gross Vehicle Weight Rating) with GCWR for the truck (Gross Combined Weight Rating). GVWR includes truck, passengers, gear, cargo, and tongue weight. GCWR adds in the trailer weight actually carried on the trailer axles (total trailer weight or GVWR for the trailer minus the tongue weight which is carried on the truck). What you need to determine is the following:

RPMs at 70mph - if it's 2k or above, you have the higher tow capacity; if it's around 1800, you have the lower tow capacity

Your actual tow capacity will be the factory capacity number minus all the gear, passengers, cargo, add-ons, and such. That means if you weigh more than 150lbs (I sure do!) your tow capacity is reduced by any amount over 150lbs, because the factory rating figures a "standard 150lb driver" as the only passenger. If you have three other people in the truck, their weights come out of the tow capacity. If you have a big aftermarket iron front bumper, a tonneau cover, step bars, added subwoofer, a cooler, or gas cans, or tool boxes, or anything in the truck, that comes off your towing capacity. Once you figure out your real towing capacity, then you can assess whether a trailer is too heavy for your truck. Here's an example:

I have a 2011 Pro4X with the 9300lb towing capacity. But I have to subtract for the following:
I'm 235lbs, so I lose 85lbs in capacity to my own weight.
I carry about 40lbs of tools and fluids in my truck when traveling.
I travel with my wife and kids, which combined weigh about 380lbs.
We bring the dog, who weighs 90lbs.
I have a fiberglass tonneau cover which weighs about 100lbs.
I have a WDH setup which weighs about 100lbs.

So my real towing capacity is 9300lbs minus the 795lbs of passengers, cargo, add-ons, and gear I carry in/on the truck, coming to a real towing capacity of 8505lbs. If I have a trailer which weighs anywhere under about 7500-8000lbs GVWR (the max weight the trailer is rated for) I should be good, as it leaves me some margin for error.

I think all Titans or perhaps all Titans except the base models have the "Tow Mode" button (I believe it's all Titans, but I'm not sure). That's not indicative of gearing at all. As has been said, if you are running around 1750-1800rpm at 70MPH in 5th gear on the highway (whether it's flat or not will not matter, as long as your speed is steady at 70mph on the speedo and you're in 5th gear and the torque converter has locked), you have 2.94 gears. If your RPMs are 2000 or above at that same 70mph, you have the 3.36 gears. This is pretty much standard across all Gen1 Titans with the RE5RO5 5spd Auto Trans (the only trans which came in Gen1 Titans).

You can also crawl under your truck and look on the passenger side of the differential snout and read the gearing on the sticker there. It will say 2.937 or something which rounded is 2.94, or 3.358 or something which rounded is 3.36. I can't remember the last digit of either number for sure, but it's pretty much as I've described.

Well, get on the highway and do 70mph. It will become obvious which gears you have.
Doesn't matter, trailer or not, nor does the tire size, unless you've added a corrector to your speedometer drive. With 1700rpms, you have the 2.94 gears and a 7200lb tow capacity, minus your gear/passengers/etc.

And you'll need to know is what your trailer actually weighs, and the GVWR of it (as that's the max weight you should ever have it weigh). As long as the weight you tow is under your calculated tow capacity by a fair safety margin, you should be okay. Dry weight of 5800+ is likely to be overweight for your truck if loaded to max.
