2015 Silverado 5.3L, 3.08 gears, Crew Cab, 33x11.50 tires

Planning to tow a trailer 2,290 lbs with motorcyles weighing 2,100 lbs for a total of 4,400 lbs about 1,300 miles each way on a trip. Total round trip will be about 2600 miles. Trailer has hydraulic surge brakes. Wanting to get some thoughts on whether this will cause any damage to the truck, or just general thoughts from you guys. Thanks

 

3.08 ratio is OK for light towing, but 3.42 ratio or more, would be better for 4400 pounds. That said, its AlWAYS a good idea to install an air-cooler for your automatic transmission fluid, when towing.

 

Damn, that's heavy motorcycle. My old '82 Kawasaki KZ550 only weighed about 400 lbs. It's a Harley-Davidson I'm guessing.

What is the Combined Gross Weight Rating for your truck? The total weight of the truck and trailer and everything in them should not exceed this rating. That said you'll probably be okay. Keep the transmission out of OD (at least when traversing hilly terrain). You don't want the transmission shifting a lot. Shifting creates heat and keeping it out of OD will minimize shifting and heat.

Personally I don't care for surge trailer brakes (common on U-Haul trailers). I'd prefer electric brakes controlled through a brake controller in the cab.

 

your owners manual has the towing limits

 

Bikes are getting heftier all the time. My Triumph Bonneville weighs roughly 500 lb. And it sure isn't a heavy duty cruiser. Just a basic naked 900cc bike. The big road bikes easily top 1000 lb.

 

OP mentioned towing multiple motorcycles in the trailer. Should have a towing weight of 5500 pounds or more, so he's good to go.
