Another Battery Question plus more

I am new to the forum but not new to camping ??

I just purchased a used 2007 Keystone Outback 27' with two slides. This was an upgrade from our 2006 TrailSport Hybrid that we simply out grew. We had the TS for 5 years with very few issues.

Ok so here are my questions and I hope the experts here can help. I did a lot of reading already but did not find the advice I was looking for yet.

I'll give as much detail as possible.

Brought the Outback home last Wednesday with a brand new Interstate battery. Plugged it in to test everything and charge the battery. We leave it plugged in at home anyway. Unplugged it at 2:00 on Friday afternoon and drove 4 hours to our camp site.

Set up and everything is great. We barely use power other than the pump. Propane fridge and hot water. In the TS we could go 6 days before switching the battery to the back up we bring with us.

So we go from Friday to Sunday at midnight and the battery is dead. I thought that was really fast based on my previous experience. I put the spare battery which was fully charged. I do need to get a volt meter to be sure though. The dealer we bought it from said the Low LP alarm would kill the battery in a week. Again strange to me. I disconnected it on Monday morning.

We left Tuesday morning at 9:00 and returned at 9:30 PM and the battery was completely dead. I connected to my truck and charged it for an hour. 7:00 this morning dead again, which o get because I only charged for an hour.

Fridge it has only
Hot water propane based
No lights on while we were gone or even when we came back. We switched to battery based lanterns and flash lights.
The booster for cable was on but I shut that off as well we have not use for it anyway
I'm at a loss for what could be draining it so quickly. What should I start with?

Next while setting up someone accidentally stepped on the emergency break-away and the plunger came all the way out. I put it back in no big deal, but with my TS if that happened a dealer needed to reset it before I could tow again. I am afraid that when o start towing tomorrow morning that the breaks will be on. Does anyone have experience with this camper and how that will work? Calling my dealer next.

Anyone use solar to charge a battery and have good luck?

Thank you in advance.

  • First thing we did when we got our new to us rig, which had a lot of new fancy things on it that our previous 1976 5er didn't have, was to test the amp use of each 12-volt devise at the battery. With the use of a cheap digital volt meter that had the ability to test amperage, we would turn on then off each devise to give us an idea of what to expect while dry camping. It also told us of the normal parasitic loads.

    In your situation, we don't know if what you are doing alone is draining the battery, or if something else is going on.

    One thing that came to my mind was if the frig humidity switch was on That would use up the battery pretty fast. Your frig may not have one of those however.
  • You probably have more draw on the 12V system than you realize. Deploying the slides is a significant drain, a radio with remote or clock has constant drain, LP detector has constant drain, Fridge and water heater both have small constant drains when on. On most break-away switches once you replace the plunger you are good to go.

    Can you finish that sentence?
  • Check converter output with no load on it. It should read approx 13.5VDC across the battery leads.

    I thought about the generator but some places we go do not allow them at all. I'm looking at the small Honda with a propane adaptor. No need to bring gas when I already bring propane.
