John, this is what I would consider. Can we afford the Single/Double and if so, you have it and since you can utilize it as a single or a double pallet handler you have it on the truck and cna utilize it in either capacity. There would be NO time lost due to changing from Single to Double as it is just the hydraulics that convert it from one or the other, NO need to change attachments. Just a thought, but reading your last post it seems you might have already decided that it not going to work for your environment.
