IF pump runs..turn it on and open a faucet.

If pump doesn't run........it most likely is in/around/near fresh water tank

I actually did that and that's what makes me think it's located in the box. I think the only way to get into that box is to remove the mattress and unscrew the plywood that supports the mattress. After that I'm not exactly sure how to access the pump inside the box as it appears to be fastened to the floor beneath the bed.
