Bought a new battery for the same problem, took it back 10 days later as it was going dead also, got it replaced with no problem. The replacement went dead in under 2 weeks. Nothing was turned on except the propane detector. Pulled the fuse for it, charged up the battery and have not had a problem since. Confirmed with RV dealer that this device does suck the juice. Just remember to replace the fuse when your using the unit, although it is a problem when boondocking.
