Scamp 13' battery life

[RogueIT]

what's the longest you've gotten power out of your battery without charging and how much power were you pulling?

Assume you are camping off the grid. No Hookups. With shore power, it is not an issue.

If it is not already equipped with LED interior lights, change them.
The biggest load on the battery may be the fridge, or the furnace.
Run the fridge on LP, while camping.
Use lights sparingly. You may get two or three nights in cold weather.

You should get at least 48 hours with a good RV battery. Add up the various power consumptions of your lights, fridge etc. Don't forget your carbon monoxide, propane gas detectors etc. which will also always be drawing battery power. Divide the power consumption (amp/hour) requirements by the rated capacity of your RV battery. Now cut this number in half because you don't want to draw your battery down more than half way or you will greatly shorten its life.
Ten LED lights will draw about the same battery power as one filament bulb so should be used if possible.
