Anderson Ultimate and aluminum truck bed compatibility

As Me-Again pointed out, all of the weight is carried by the bed of the truck when using the Andersen Ultimate hitch. I'd have to look in depth at the truck bed to see if I thought it would hold up to the weight and potential flexing. Personally I probably wouldn't use one with 5er of any size if I had an aluminum bed. That said, I would avoid the aluminum bed if possible as I use my bed for a lot of stuff, much of which would seriously scratch and gouge aluminum.
