Mystery beeping sound

[Alaskaman]

Purchased a new Carbon 417 last fall, never been on the road yet. Today while shoveling snow at the front of the unit there is an audible beep every ten seconds. I can hear it clearly in the LP cabinet and battery compartment but cannot find the source.


I called the dealer, he thought perhaps the batteries were low....I keep it plugged into AC power full time, except for perhaps the last week it was left unplugged for about a week. I disconnected the battery + jumper, the beep continues.


the only thing on in the 5er is a fuel station warning that it's low on fuel, I cannot figure out how to disable it, pulled fuses in the main panel, it stays lit.


Any thoughts on the beep and how to turn off the low fuel level light in the control panel?


The documentation that came with this brand new toy hauler is next to worthless. Talking to the dealer he says that's it, there is no serious documentation on these, only for the fridge and AC units.


Thanks
