Good call by "Just George". The pump is pretty easy to change, just hard to access. It requires you crawl into the 3/4 bay on the passenger side. Get a pair of hose clamps (Amazon) that lets you clamp the coolant hose was replacing the pump. The pump that is bad should be about the middle of the unit as you're looking in.
Tip.....when traveling between campgrounds, turn off the electric and diesel burner switches on the Oasis panel.
