Adjustable height leveling leg
View Patent ↗A leveling leg assembly adapted for mounting to a vehicle includes an outer member and an inner member telescoped slidably into the outer member. The inner member has a first end extending beyond the outer member. The inner member is telescopically driven out of the outer member from a retracted position toward an extended position. A first bracket is fixed to the outer member, and a second bracket is fixable to the vehicle, wherein one of the first and second brackets has a plurality of holes formed therethrough, and the other of the first and second brackets has at least one hole formed therethrough that is aligned with at least one of the plurality of holes to fix the first bracket relative to the second bracket at a desired height relative to the vehicle. At least one hole of the plurality of holes formed through the one of the first and second brackets is not aligned with the at least one hole formed through the other of the first and second brackets to provide an alternate mounting height for the first bracket relative to the vehicle.
