Safe towing starts before the trailer is attached. Matching the hitch ball size is only one part of the setup. The vehicle, receiver, ball mount, ball, brake system and loaded trailer all have to work within their individual ratings before you leave the driveway.
What Gritmoor trailers require
- 2 5/16-inch ball hitch (required on all three trailers)
- 7-pin trailer connection (powers trailer lights and brakes)
- Functional brake controller in the tow vehicle (electric trailer brakes are on all Gritmoor trailers)
- Properly rated receiver, ball mount, and hitch components for the loaded weight
A 2 5/16-inch ball is available to rent for $10, but the renter is still responsible for verifying the complete towing setup.
Check your specific vehicle, not just the model
Tow capacity varies dramatically by engine, axle, cab, bed length, drivetrain, and factory tow package. A half-ton truck with one engine and axle configuration may be rated to tow 9,500 lb. The same truck with a different engine or rear axle ratio may be rated at 6,500 lb or 13,000 lb. The number printed in marketing materials may not be the number for your specific truck.
How to check your actual rating:
- Find the sticker on the driver's door jamb—it shows GVWR and sometimes the tow rating
- Check your owner's manual towing section (the table usually breaks it down by configuration)
- Look up your VIN using the manufacturer's towing guide, which accounts for your specific build
Payload and tongue weight: the often-missed check
Tongue weight is typically 10–15% of the fully loaded trailer weight. A loaded 7×14 at 10,000 lb creates roughly 1,000–1,500 lb of tongue weight. That tongue weight counts against your truck's payload capacity—which is also reduced by passengers, driver, fuel, and any cargo in the bed.
A half-ton truck may have a payload rating of 1,500–2,000 lb from the factory. If the truck is already carrying 800 lb of tools, gear, and passengers, it may have very little payload left for tongue weight from a large loaded trailer. Check the payload label on the driver's door jamb.
Brake controller basics
All Gritmoor trailers have electric trailer brakes. Your tow vehicle needs a brake controller that is compatible with electric trailer brakes—either a factory-installed controller or an aftermarket unit plugged into the 7-pin connector. Towing without a functioning brake controller is unsafe and in most cases illegal for trailers with brakes.
If you are not sure whether your vehicle has a brake controller, look below the driver's side dashboard. Most factory controllers have an adjustment dial or display. Aftermarket units are typically mounted on the dash or under the dash with a small display.
When delivery is the right call
If your tow setup is uncertain, ask about delivery instead of assuming a smaller trailer solves the problem. A lighter trailer reduces tow requirements, but if the vehicle is genuinely not set up for towing, a smaller trailer is still a risk. Delivery removes the towing question entirely and is available for most cities in our service area. Send the project city, dates, material or task, and the equipment you think you need.
