    So my dh encountered this when he picked our pup from storage, but we haven't solved the mystery yet and I'd love some insight/thoughts/suggestions before we take it out this weekend.

    The pup was stored without it's battery, but the propane was still attached (and apparently not shut off). When dh hitched it up to our tv - he connected the electrical and the camper furnace turned on! The pup was closed up and he immediately shut the gas off but it took quite a while for the fan to shut down. My theory is that our thermostat must have moved during transit or from storage to our tv, to the on position. Our thermostat does not have an on/off switch - just a moveable temperature gauge. Also I guess the furnaces use electricity to run the fan (ours growing up did not), but the camper was down so shouldn't the kill switch have not let this happen?

    How can we stop this from happening in the future? If dh hadn't caught it or it happens while we are on the road I fear our pup would end up in a ball of flames at the side of the road...

    Your thermostat probably does have an off switch. If you slide the dial all the way down it will click over/slide over a hump which turns it off. I didn't know about it until it happened to me last year.

    You are right - it is off when the temperature is all the way down but there isn't anything to keep it there (no hump to pass over to hold it off).

    Slide it hard, mine was tough to get past the hump, I thought it was going to break. I upgraded to a digital with a battery

    Thanks! I'll give it a try. Fingers crossed that's all it takes :)

    My 08 Rockwood does that when I connect the battery the first time in the spring.
    I have tried and tried to figure out why. The thermostat toggle is all the way to the min setting. It can't go any farther. My only theory is that it's some sort diagnostic or some such cycle. It doesn't turn on like that again unless I disconnect power completely and hook it back up. Also, when it does this I have never heard the igniter activate either.

    I'd wire the furnace or thermostat through the kill switch.

    My water pump was not and a bump caused it to come on [:(O]

    My nephew's Starcraft has a switch on the swing up galley that makes the circuit to the furnace. This insures that the furnace will not come on when the camper is down. I'd think you may have a faulty switch somewhere thats not breaking the circuit when down.

    or the switch is working, but packed to the gills with something that puts some pressure on the switch ?

    Thanks everyone! I took a much closer look at the thermostat while we were camping this past weekend and found that if pushed hard enough, it does switch off!! I had to take the faceplate off to figure this out lol). I think the furnace must not be wired through the kill switch. The kill switch is working fine for the lights, etc. when I tested it and the pup was empty when we stored it.

    I'm glad to hear that this also happens to another when picking it up from storage - now that I've found the off switch for the thermostat, I'm not so panicked that it will just randomly start when we are en route somewhere.

    The good news is, the propane is usually connected to the kill switch. So, even if the furnace did come on, it would not ignite.

    If it comes off easily, take off the furnace grill. The furnace in my PUP has an on/off switch on it under the grill.

    I've never seen that. In order for that to be true it would require a solenoid controlled valve to be in the propane line. I've only seen that on a few motor homes, never on a small trailer.

    I will take the furnace grill off and check for a switch when I have it up next week to pack for our next trip - that would be very functional if it did! Also our grill rattles something fierce when the furnace fan is on so I'll try and address that at the same time :)
