Common Questions
Answers based on our research and real owner data
What can a 2025 Sierra 2500 HD actually tow?
It depends on which configuration you get. The 2025 Sierra 2500 HD ranges from 14,500 to 20,000 lbs. That's a big spread! The difference usually comes down to cab style, drivetrain, and engine choice. We always recommend staying around 80% of your max — so 16,000 lbs for safe towing.
Which configuration should I pick?
Start with what you're towing. If you know your RV or trailer weight, work backwards. Generally, 4WD adds safety at boat ramps and campgrounds but reduces towing capacity slightly. Crew cabs give you passenger room but less payload. Check the table above — we highlight towing and MPG so you can compare at a glance.
How does payload affect what I can tow?
Here's what catches people off guard: tongue weight counts against your payload. For bumper pull trailers, that's typically 10-15% of the trailer's loaded weight. So if your trailer weighs 8,000 lbs, you're putting 800-1,200 lbs in your truck bed. Add passengers and gear, and payload fills up fast.
What hitch do I need for a Sierra 2500 HD?
For the 2025 Sierra 2500 HD, we recommend a Class V receiver hitch. It's rated for the full towing capacity of 20,000 lbs. Don't skimp here — your hitch is the critical link between truck and trailer.
