Question:

I am looking for the hitch with the most ground clearance and concealed the most. I will also need a wiring harness to a 4-pin connector for a boat trailer. I’m also interested to hear about suspension options. This will be for a 2020 Toyota Sienna XLE AWD. Thanks in advance for the information.

I'd be happy to help with that.

Let's begin with the hitch. For the most concealment/ground clearance I'd recommend the Curt class III hitch, part # C13343. This hitch will be mostly concealed, with the crossbar being hidden behind the bumper/fascia. The only visible portion of the hitch will be the receiver tube and the safety chain loops.

For a 4-pole trailer wiring harness, I'd recommend the Tekonsha # 118648. You'll also need a ball mount. The average leveled height of a trailer coupler is around 16-1/2 inches, so if that's the case with your boat trailer, you'll need a ball mount with a rise of about 4 inches like the Curt # D-28. You'll also need a # PC3 hitch pin or a locking hitch pin like # e98882. For a trailer ball, use # 19260 for a 1-7/8 inch or # 63845 for a 2 inch ball.

For rear helper springs for the coil springs on your Sienna, I'd recommend the Air Lift # AL60732, which will provide up to 1000 lbs of additional support for your rear suspension.

I've linked to installation videos for the hitch, the wiring harness and the helper springs I recommended.
