We also have a 97 TM, and our LP gas detector beeps when the TM battery gets low.
I posted about this a while ago, after we spent the night in our TM in a prolonged power outage using the TV, furnace, etc. and the LP gas detector drove us back into the house at 4 am or so with it's loud beeping.
I have mixed feelings about the LP detector, we lived without one for many years, and it is annoying when it goes off in the middle of the night. However, it is a good indication of the state of your battery, which shouldn't be discharged to that state, if you want to keep it in good condition, as I have learned from the wonderful posts of the members of this board.
The advice on the previous post by Paul echoes what I have experienced.
Paul, do they still have that great burger place up there, Burger Depot? That's about our most favorite burger place in the state, besides Happy Hound in Los Gatos. We have spent weeks up in your neck of the woods and plan to do a few this summer!
