THANKS! It was a lot of work, but well worth it. Now if we didn't have to work for living.. would rather be wandering all over the place in the darn thing..
Many, many hours went into just the planning. I would go out into the shop, and there was all my guys (Mr Gimli included) standing around staring at the truck with the old brain gears just a burning as they planned and planned. Several times Mr. Gimli would sit on a 5 gallon bucket in the middle of the steel frame that was to become the box, and contemplate how everything was going to fit and how it would work together. You are basically building a house! A heavy duty off road house.
Mr Gimli is one of those that doesn't "need no stinkin drawings" and this was all done from his little pea brain. (hope he doesn't read this...)
Anyway, unless you have one of those brains like his, it might be best to make several drawings or schematics of wiring for lights, plumbing, etc. And of course, be prepared to change everything at least once. Take your time, and do it right the first time. Just like the condition of the truck itself, you don't want to go out on an expedition and find out that your fresh water just peed out on the ground because things weren't plumbed right, and no, that did not happen to us. But I hope you see my point.
Our main problems were the inverters for solar power (the cheapo inverters aren't even worth the trouble of installing), and nasty gases from the black water tank during travel.
Better quality inverters work better, and we got a funky wind-directional-vortex-twirly-thing that goes up on the nasty tank vent (we tell people it's a wind direction finder for biological warfare avoidance). You might think of using a good old fashioned porta potty set up. Doesn't take up much room but privacy is lacking.
Please let us know if we can help with anything else. Main thing - have fun with this build!
