3 - Way Fridge 2

Since my van didn't come with either fridge or stove, I needed to cut a hole in the side of the
vehicle to accomodate the vent and two more for the water and AC/Mains inlet.

I used a jig saw and had no trouble at all.

The Vanagon/T25 had a pair of fuses behind the driver's seat and a relay in the line as well.
I did away with both. I fused the DC feed at my Leisure battery's fuse panel and I like to make my own
decisions about when to run the fridge on DC.

The factory installed the relay to make sure the fridge couldn't get DC power unless the engine was running.

A note on this. The fridge doesn't cool well on DC and is rather hungry at about 8 amps draw.
Let's say you have a good DEEP CYCLE battery which is rated at 100 Amp/Hours.
If you run the fridge and nothing else, in theory you can run the battery flat in 12.5 hours.

In practice, it will be a much shorter time. Even a deep cycle battery shouldn't be 100% discharged.
On top of that, you may not be able to recharge just from driving and even if you can, you're pumping too much
juice into the battery. I think there's a whole explanation of this elsewhere on the site (I don't visit my own site much).

Feel free to email me if you think I should expand on the battery thing but do me a favor,
don't email me to try to convince me that your regular starting battery is fine for this purpose.
