Your first experiments on the probably partially drained battery, i.e. running the jacks up and down three times, pulling the awning in and out, and turning on all the lights may have used up over half of your battery's capacity. BTW, check out LED light bulb replacement if you have incandescent bulbs OEM.
As was posted, take a trip to Harbor Freight or one of the big box stores and get a cheap meter. It will also be handy for diagnosing issues in the future. The learning curve is short and shallow. A clamp meter that measures up to 200 amp DC is the real deal. I recommend this one:
AC/DC Tenma Clamp meter
