How to Determine Correct Trailer Ball Height for Towing Small Fishing Boat

Question:

How we determine the correct for a ball mount hitch? Our Tahoe hitch is much higher than my brother-in-laws Honda Pilot.

To determine the rise or drop needed, jack up the trailer so that the frame is level to the ground. Measure from the bottom of the coupler to the ground. Then, measure from the top of the receiver opening on the trailer hitch to the ground. The difference between these two measurements is the rise or drop needed. If the receiver height of the Tahoe is greater than the coupler height of the level trailer, you will need a ball mount with a drop. If the level trailer coupler height is greater than the receiver height of the Tahoe, use a ball mount with a rise.

You might find that a ball mount with the exact correct rise or drop is not available. If this is the case, get as close as you can. As long as you are within 2 or so inches of level, you will be fine. Its is preferable to have the trailer ball a bit high than too low.

I have linked to our FAQ article that will show you exactly what to measure to determine the rise or drop needed.
