I don't have any specific knowledge of this model, but I did a quick search and found some interior pictures of that model for sale here:

It looks like in that area there would be hot & cold pex tubing run up to the sink faucet, an ABS drain line from the sink heading back to the gray tank, and a propane line running up to the range/oven. I would not expect any pumps to be in that area, they are typically installed close to the freshwater tank. It also appears that the hard wired propane leak detector is installed at the base of the three drawer cabinet, so it might be worth verifying that it or its electrical supply wiring was not damaged.
Good luck with the repairs. I personally would request some before and after images if you are not able to inspect the damage personally.
