I asked the same question of our salesman before we went to pick up our 2021 G16BH with the off road package. He measured it at around 24-25 inches in the parking lot. That should get you in the ball park, because he didn't do this on level ground and make sure the trailer was absolutely level.
I havenít been everywhere, but itís on my list.
