In keeping with a lightweight design.

I made these adjustable lift blocks out of redwood rems. I can adjust them in 1/2 inch increments. I have 2 for the back of the trailer. And one for the front tongue. Since the trailer is Very light I can just lift with one hand and slide a jack under the trailer. For the trailer jack in front. It slides in place and I lift the tongue to set the height. The extra block on the top of the front tongue jack, allows me to move the trailer without taking off the redwood lift jack.
I also did a small trip to see how the trailer tows, and to get a idea of gas mileage. I went over two mountain passes in a 180 mile trip. I got about 28 m.p.g.
