[T2] Coolers, Fridges, and Electricity

[c.dreike]

All good comments. The inverters do draw a small amount of current even 
when nothing is plugged in to draw power. You don't want to leave them 
hooked up to a non-charging battery for more than a couple of days.

The higher the rated output, the more this latent draw is - Example: I had a 250 watt inverter to run a boombox.  Powered it off my lighter socket with a regular lighter plug (as supplied with the unit), no problem.  I then decided I wanted to electrify my rig, so put in a 1500 watt powerhouse , and to test it, and used the lighter plug and wires to test it.  Bottom line - the plug (or wires, I dunno) weren't enough to  allow enough juice for the thing to even power up!

You really don't want to pull your battery dry out in the middle of a campout in BFE.

Install it just like you would household electrics - junction boxes, conduit (well attached to the underside of the pan or however you decide to run it) etc.  This is serious business - it's less about "electrifying" your bus than having a wire overheat and giving you a not-so-nice tear-jerker of a bonfire, so DO NOT SKIMP on this part.

It was, honestly, a PITA to do, but when all was said and done, it was *well* worth the frustration.  (That one had a 1 KW unit in it that ran nearly everything, set up to my deep cell battery and charged off the alternator.  ad power from the bunk to the kitchenette to the dashboard.  And yes, I'd do it again!)
