Common Questions
How much can I actually tow with my 2017 GMC Sierra 3500 HD SLE?
Your 2017 GMC Sierra 3500 HD SLE can tow up to 20,000 lbs according to the manufacturer. But here's our advice: stay around 80% of that (about 0 lbs) for a much better towing experience. You'll have room for hills, headwinds, and those unexpected moments on the road.
What about payload — how much stuff can I put in the truck?
You've got 5,955 lbs of payload capacity. That's everything that goes IN your truck: passengers, camping gear, coolers, and don't forget — the tongue weight from your trailer counts too. It adds up faster than you'd think!
What kind of hitch do I need?
For your 20,000 lbs towing capacity, you'll want a Class V hitch. Make sure whatever hitch you buy is rated for the weight you're actually planning to tow — not just the minimum. A little overkill on the hitch is always better than not enough.
What types of RVs will work with my truck?
With your 0 lbs safe towing capacity, you're looking at a great selection of travel trailers and many fifth wheels. We've put together a list of compatible RVs above — take a look and see what catches your eye.
What does GVWR mean and why should I care?
GVWR stands for Gross Vehicle Weight Rating — yours is 13,025 lbs. Think of it as the maximum your truck can weigh when it's fully loaded with people, gear, fuel, everything. Exceed it and you're putting extra stress on your brakes, suspension, and tires. Not worth the risk.
