First, you need to find the height of the trailer's tongue when the trailer is level. Set up the trailer on flat pavement. Run the tongue jack up and down or prop it up on some scrap lumber until it's level. You can determine this by placing a carpenter's level on the tongue or by eyeballing the trailer from the side from a distance of about 50 feet. Measure from the ground to the top of the ball socket. Park the vehicle you'll use to tow the trailer on level ground too.
Two years ago, the Truckee-Donner Land Trust purchased the Summit Canyon area at the foot of the pass so that now the entire pass area is open space. The Old Lincoln Highway trail is now a great hike that winds down through the historic Donner Pass area.wo years ago, the Truckee-Donner Land Trust purchased the Summit Canyon area at the foot of the pass so that now the entire pass area is open space.
