Did you note the results? If so, how about telling us about them?

I have to say, you're weird, bizarre, possibly mental etc.... That said, I did the same thing when I installed my panels earlier this year. Worse yet, I wasn't even camping, just parked out front of the house, ran them down to 50 percent according to my trimetric overnight, then went out at the crack of dawn t0 see what sort of output I got prior to sunrise and verify battery state of charge, then periodically checked throughout the day as the sun rose.
I'm hoping to have my RV pad poured and should probably take some pictures and show my install as a contribution for whatever it's worth to the forum. As for what I recall from the first day.
Mountains to the east, so it gets fairly light out prior to the sun breaking over the mountains. Solar output reached about 1.5 amps prior to the sun hitting panels direct. (Battery switch off so all pwr to batteries) With 5 100 watt panels on roof, parallel wiring and only tilt being curvature of roof the current jumped up to 7 amps when sun broke over the mountains. Hit 34 amps by 10am maxed out at 25.2 then dropped down around 24 amps until it started dropping fairly quickly until the charger dropped out of absorb when batteries hit 85 percent according to the trimetric. Voltage dropped from 14.8 to 13.2 and current down to around 8 amps slowly falling off from that as I recall. I hit 100 percent on around 3pm (3 Group 24 batteries, started at 49 percent state of charge according to trimetric.) Temperature at Sunrise was approx. 68 degrees climbing up to 91.
