The door sticker only says tires psi and that the vehicle and cargo should not exceed 1745lbs.
It's a V8 but I have no idea what size. It's not on any paperwork I have. C1500 LT is the model
Cargo is not towing. Cargo is what you have inside and in the bed of the truck.
Your tires and shocks/sway bar setup/brake pads have more to do with tow capacity than engine power.
With a stiff cargo tire pressured up right and the optional trans cooler if not factory equipped, I would look at 7000 as the upper limit of comfort myself. (with good working trailer brakes and a real controller...not a cheap "timer" unit...)
I have a 2003 1500 Silverado with the 5.3.
I regularly haul classic cars on my 2300 pound car trailer. 5,000 pound vehicles and 2300 pound trailer is no problem. I have stiff sidewall tires however. Cannot stress enough how much of a handling advantage these are when it comes to towing.
A camper van on that same trailer that I junked and weighed at the scrapper---(6400 pounds)---was a bit much.
There was more than enough power to pull it, but the suspension was clearly edging out of its comfort zone.
Your frame and running gear can be configured to tow up to 9400 pounds according to the fleet info sheet.
I would never tow that much with a 1500 chassis, though.
There should be a trailer button on the shifter. Always use it when towing any trailer over 1500 pounds. Makes the load easier on the trans.
Some people will tell you to "pull it down out of overdrive on the hills." This is hogwash. If it tops the hill in OD without shifting back and forth in and out of OD, let the computer do its job. The only time you want to force it to use a lower gear is under oscillating conditions.
Do not be afraid of "overworking" your truck.
Those engines are, quite simply, the best gasoline workhorse style V8 on the planet at present time.
If you have do a 2016 V8, it should be the 5.3. (75% of them are 5.3's)
This means you would have 350-ish HP and 375-ish ft lbs of torque.
To put this in perspective, this is more HP and just a little less torque than the old carburetor-fed 454 engines that power 34 foot long class A units.
(My class A has this engine. I gross out at 25000+ pounds on the scale.)
Distribution/anti-sway hitch, tires, if squatting...a set of air bags can turn a truck from a "spineless jelly-fish" into a rock-solid performer when trailer towing.
If you PM me your VIN, I will tell you exactly what engine it is.
