Most owners know the problems related to stabilizing trailers at campsites. Sometimes you need more blocks to put under those four jacks. I came up with a simple solution that solves two problems — limited storage space and not enough blocks.
I made a pair of wooden boxes that are just large enough for one 6×6-inch leveling block to nest inside each one. The sides are built of 2×6-inch lumber, and the bottom is plywood. When I need to elevate a jack more than 6 inches, I stack a block on top of its nesting box.
The two boxes and two leveling blocks do the job of four blocks, but when nested, they take up about half the space, which makes more room for other gear.
