Tongue Jack Block - Need one light, strong, and tall

I've used a piece of 10 X 10 wood about 14" tall and usually put it on a piece of 1 X 10 for stability and to keep the dirt off of it. Works for me4 with no less than 28 years of trailering. We have traveled across the USA no less than 12 times and set up more than I can think with nothing fancy just wood.
