Is the fridge on 12V or propane? If it's on 12V that's likely your problem. That heating element draws a lot of juice - run it off of propane unless the engine is running to charge the batteries. When on shore power obviously use 110V.

If the fridge is on propane and you're sure there's nothing else on to draw it down then you may need to replace the house batteries.

I assume the water heater was not on electric?

Do they make 12-volt electric water heaters? Or an inverter issue?

Most "new to me" units come complete with dead batteries.

5.5V is dead and the battery will quickly become bad at those voltages.

How many and type of battery and what loads did your run? Seems like you need to become much more aware of and manage to your setup.

Batteries have limited power and shouldn't be discharged below 12.1V or you will be buying lots of new ones.

Be interesting to know what is mean't by "the batteries".
Type, how many, etc.
Has the electrolyte level been checked on the batteries.

Good point, have the battery load tested at a auto store.

My 2 year old "new to me" rig came complete with 6 bad batteries which were replaced at the owners cost. Still going strong after 5 years with good management.

If you boondock without shore power, then it behooves you to maximize battery capacity.

I'm having great luck with my used Telecom batteries. I've had them in service for a year now and I push them hard.

They are taller than golf cart jars, but being AGM can be installed sideways. I'll certainly go with them again, since I can't afford my "ultimate" battery which would be six 2 volt AGM's with 900 amp-hours of capacity.

thanks for all the feed back yes the refrig was running on LP. guess I need to have the batteries tested the bad side is I don't dry camp much hate to put out a lot of money just to have them go bad again.

I have 2 12 volt deep cycle batteries

You don't have to bother testing them if they won't hold a charge. A $12 voltmeter will tell you that.

What do you mean 'have them go bad again?'. They should hold up at least 4-8 years with proper maintenance.
