I have a FunFinder also by Cruiser RV with an outsicde shower. If your shower hose, like mine, stores by pushing the hose into the body of the camper, it probably goes into an interior compartment. The internal compartment in my camper is where the water pump is located along with the converter, slide control, etc. A panel, screwed in place, seals this compartment. By removing the screws/panel I can inspect the content. It has happened that the shower house has hung up and gotten kinked thereby stopping the water's flow. I suspect you may have a kink in your hose. If you can access it from inside the camper, you can probably easily correct the problem.
