Hey all, last night I disconnected the shore power from the trailer and let it sit idle for 12 hrs. My voltage started at 13.7 and ended at 12.4. The only things running were the Carbon monoxide detector, stereo (off position), and the fridge which was running on LP.

The batteries I'm running are the 6 volt Interstate GC2 Deep Cycle Extreme (GC2-ECL-UTL) 225 Amp hours 115 min @ 75 Amps.

Looks plenty good to go camping.

I will say if mine has been in storage for a while the first day seems like a bit of an extra drop in voltage. By the 2nd and 3rd day with a little exercise the battery performs better.

Those are good results--but did not include running the furnace. It is by far the most 'hungry' device.

I'd double the battery bank and add 150 watts of solar.

Today I hooked up a single 100 watt panel and it was an overcast day.

At 9AM I decided to turn the heat on, I ran it for 20 min and checked the battery voltage, 12.2 while heat was running and back up to 12.5 after the heater shut off.

I then turned 3 interior lights (all LED's) on and checked after 2 hours, batteries @ 12.8 volts, still overcast.

Turned off the lights set thermostat to 60, batteries @ 13.1 volts.

Started to rain about 3 hours ago and it's 6:30 PM, heater still set @ 60, batteries @ 12.6 volts.

Again, I only ran a single 100 watt panel on an overcast day.

I'm excited to see what happens once I get all three 100 watt panels hooked up [emoticon]

I would like to increase my bank size but my only issue is, my single axle trailer only has a 508 lb payload. I think adding 120lbs of more batteries would put me over. I guess I could throw them in the back of the truck though.

Been meaning to disconnect my solar and cycle my batteries. Will get some rough numbers for ya tonight or tomorrow.

So no generator right? Like others said your only real variable will be how much heater you can run each night. One of the portable propane heaters might really come in handy. Or a small genny if you can make noise at night/early morning.

I have the same clamp meter linked on page 1. This is the amp draw using 2 fully charged 6v's. I think theyre the newer version of your batts. The costco interstate but only 210ah.

With the trailer turned on it pulled 0.18a just resting. That small 0.2a draw is included with the numbers below.

Fridge: 0.97a
Water Pump: 4.87a
TV and Stereo: 3.7a
Furnace: 5.25a
Bunch of white LEDs: 3.40a
Color Changing LEDs: 1.3a

Something to recognize:

Measuring voltage while something else is connected is highly deceptive. The higher the other load, the further off you will be. That includes your gas/smoke detectors.

Gas valve Tuna? I can pop my cover and test it. I noticed the fridge pulled 0.7a and then bumped to 0.976a. Seemed to hold that .97a number for a couple minutes. I dont know if the fridge fan turned on. Its not warm today.
