Cribbing - 6x6 or concrete blocks
Well, there's a chill in the air, and there's only 6 weeks or so of camping season left. So I'm thinking - we have a new 5er with the 6 point leveling system. Directions say to clean/lube frequently. Gonna be difficult to do while in winter storage (several miles from home). So I thought I would use enough cribbing to keep the front hydraulic cylinders retracted as much as possible. What would you all recommend: 8x8x16 concrete blocks stacked (changing direction with each course as required) with a 2x piece of wood on top, or a bunch of 6x6 pressure treated lumber in a traditional cribbing formation?
