Hi! It's me! I bought my very first ("vintage") RV last fall, and have been on the road since. Sold my house, my car etc etc. It's just me and my critters (3 dogs/2 cats/1 grumpy 45 year old lady!) Ok....promise not to laugh? I have a couple of SO basic questions I'm embarrassed. I'm in a 1978 Coachmen Leprecaun. After a winter (warm, luckily since I've been on the Oregon Coast since mid-November), I notice that there is some kind of heater thing under the "couch". Seems to be hooked up to the vents (circular) that I always thought were just...well...airholes?!? (You promised not to laugh!!) I can't seem to get the cover off of this heater thing. Says Coleman on the side .... Second. I've been "plugged in" everywhere I've stayed so far. Ya know, electric/sewer/water/cable. There's a power inverter next to the circuit breaker box on this, and when I bought it the guy told me that I needed TWO new batteries so it would work right (got those). I'm confused about the inverter thing. It BUZZES something fierce all the time, beyond what I'd call 'white noise'....I have to turn the TV up extra loud to hear over it for instance. I don't see any kind of shut off on it, and don't know if I need it on anyway. None of the cord-thingies that go into it will unplug, and when I flip the one circuit breaker off that seems to control it, I also lose power to a couple of outlets (regular plug in outlets). SO.... what IS this Power Inverter thing, do I need it? Can I safely rip out one of the cords on the side of it so I can get rid of this buzzing? I'm NOT stupid (really!!!!!!!!) I have a Masters Degree (in Biology) even!!! But, I'm kinda naive about a LOT of mechanical stuff, and I sure don't know ANYTHING about the innerworkings of this!!! I'll have more idiotic sounding questions in the future I'm sure!!! Thanks you guys!! RV-folks are just the greatest!!!!
