2021 Toyota Sienna hitch questions
Which trailer hitch fits a 2021 Toyota Sienna?
CURT 13470 is a Class 3 hitch with a 2-inch receiver, rated to 3,500 lb gross trailer weight and 350 lb tongue weight.
How much can a 2021 Toyota Sienna tow with this hitch?
The hitch is rated to 3,500 lb gross trailer weight and 350 lb tongue weight, or 5,000 lb with a weight-distribution hitch. Your Sienna has its own tow rating in the owner's manual, and the lower number is your limit. A loaded bike rack counts against tongue weight too.
Do I need a wiring harness for the 2021 Toyota Sienna?
If a trailer is going on, yes. Brake and turn signals have to work, and CURT 56458 plugs into the factory connector so the trailer lights follow the Sienna's. Order it with the hitch and it's one install.
