Need advice on wood gassers... Newbie here

thanks. got a local guy that refurbishes pallets and he build me ones like in my avatar.What i have found is they don't like uneven ground. Once in a while I get off center of pallets and break one or two. But i can stack them pretty easily(like in the pic). In the future i will be building them out of steel. Or, pour an outside slab to stack them on? Doubtful. But, if you take a few minutes you can build your own wooden ones for next to nothing.

Also, a three point mounted pallet lift works very nice for the price. A small compact tractor can lift a pallet of wood off of the 3-point.
