I went to Folsom Lake SRA with my son for my first overnight outing with trailer.
Everything went smoothly.
I did forget coffee cups.
Shown below is a photo of me in front of the trailer.

Shown below is a photo of my son.
The maximum inside height is 5' - 10 1/2" or so.
He is 5' - 11" tall.
He has to watch the clearance.
I am 5' - 9" tall
I have no problems with the inside height.

I use a Toyota Sienna to tow the trailer.
It handled the trailer with no problems.
Thursday, my wife and I are traveling North.
We will stay one night at Antlers RV Park.
Then, we will head to Portland for 5 days or so.
We will then go back to Antlers RV Park to attend the Dam Gathering.
