Stop in for a cup of coffee

I put it on a wheeled cart. BUT I was concerned the wheels would bend thru the aluminum bed. So I put a piece of wood under it. Will probably bust thru the wood and the bed!! But I do not know what kind of help I will have unloading it. And the wheels make it easier to bring to the back. Could have left it in the back but would be an unstable load for that kind of distance...
I would put a couple 2x’s under the cart to stabilize it. Or remove cart. Then drag it back with a strap when unloading.
i dont trust anything with wheels in the bed of a truck.
