Crappy stock batteries or something wrong?
We have been loving our Thor Challenger since we picked it up in July, but one thing that eats at me is how long our batteries (don't) last. It seems that anytime we are boondocked overnight the batteries get dangerously low, and have twice gotten low enough where I needed a jump to be able to start the rig. Thank goodness for Good Sam Roadside! The display shows BOTH the house and chassis battery levels get quite low. The last time we had to jump all we had running overnight was the heater (it was around 40 outside).
Is this a result of crappy stock batteries that came with the rig? Should I get some nice interstate deep cell batteries (had them in my previous Class C and they worked like a champ!)? The water level on the batteries is fine. Is there something that I should be doing when I am boondocked overnight that I might not already be doing?
Thanks in advance for any thoughts!
