AMP Draw Issues
Good morning Folks! I am hoping someone can point me in the right direction... We have a 2005 Keystone Outback 26RS travel trailer and did our first dry camping last week. When the heat quit about ...

My trailer idles at 500 milliamps running the fridge. I call 650 normal. Fridge does not take much either (200 milliamps?) unless you have a humidity control that is on.
I assume you charged the battery at home and were running the fridge and some lights while camping. Was the battery near dead before you charged at home? Lead-acid really likes to stay 100% tip top charged for longest life. If the battery was allowed to sit partially discharged in storage it may have sulfated and permanently lost some capacity.
I assume you have a WFCO converter and just saying these generally operate at a fixed 13.6 volts. This is just a trickle charge and will take 24 to 48 hours to charge a low battery. Battery really wants 14.4 to 14.8 volts for charging properly in reasonable time.
Typical dealer just pops in a small group 24 with 80 amp/hour capacity. For off-grid camping you probably need 2x group 27 or 2x GC2 for closer to 200-230 amp/hours.
