Bigfoot 25c 10.4 long bed

Congratulations on your new Northern Lite Camper! I’m sure you’ll be very happy with it. As far as the water in the propane compartment, Bigfoot does not install a bottom seal to allow propane to exit the compartment in the event of a leak. The floor of the propane compartment is plastic. Unfortunately,this also allows water in. Many owners have installed a aluminum angle with a gasket to stop the water. The basement should not have water at all! Perhaps the dealer neglected to lock it prior to a rain storm. The battery box on the newer 10.4 models was re-designed. I believe there is a sliding tray in the compartment to allow for 2 batteries. I can’t see Bigfoot only having 1 battery and 2 propane tanks.
Best of luck to you
