Hey everybody,here comes a few more questions.we made our first camping trip this weekend and it was a blast being in a pup except when the winds started going high speed. It rained big time and no water leaked anywhere,so here go's...I'm posting 2 pics...one of the top of the door frame that has two slots but don't go anywhere and the 2 switches under the fold down sink, the switch on right go's to the lights and I think the one on the left go's to the heater but not sure,was afraid to play with left switch cause heater worked great and didn't want to mess anything up. What do u think.....tks
