Things I have learned during the progress of construction..

1. My carpentry has improved greatly but needs further improvement. It's perfectly functional but I need to learn how to make proper joins in wood rather than relying upon steel brackets, bolts and OSB panels screwed to the beams.
2. Internet forums are completely useless, full of asinine opinions, dangerous suggestions and aggressors that call my carefully constructed motorhome all kinds of names - when they're not being abusive to me personally.
3. US plumbing sizes are rather fictional. I measured a 1.5" right-angle tube at 1.75" with my tape measure - and that was the inside diameter. To find plumbing bits that fit, it's necessary to go in and try things rather than to rely upon what's written on the item itself. 
4. US electrical systems are reasonably straightforward though the electricians that install things are not to be trusted. Better to look up how to do it and to do it yourself.
5. Rustoleum (Hammarite in the UK) produces the world"s most useless paint. If it can be avoided then do so.
6. Latex paint is for ceilings only.
7. Silicone sealant works but nothing sticks to it - way better to use latex sealant.

Today was a shopping day so it was a trip to Lowes (hiss, spit). I came to the conclusion that despite the fact that Lowes is unbelievably dishonest, since the nearest Home Depot and Tractor Suppy are 8 miles further and hence (even at $1.67 per gallon) an extra $1.50 to get there and an extra half hour in insane South Carolina traffic.

So, the upshot was I got enough cable to complete 60 feet of cable from the power post to my bus. I also got sufficient plumbing supplies to complete the plumbing underneath the bus. The termination in my plumbing will be a simple stopper screwed into the bottom of the line. That's just going to be there in order to stop critters from crawling up when it's not in use. 

Before I did any of that, I cleaned up the steel plates that will be welded ito the battery compartment using an abrasive brush in the pistol drill. That removed most of the rust. Then I slapped Rustoleum primer for rusty metal. If that kills the rust as well as primes, I'm happy. I rather suspect it'll be just as worthless as the rest of the Rustoleum product range.

The plan is to complete the plumbing, continue working on the battery compartment in the background, reseal one seam on the bus roof, work on the peeled paint, install shower curtains and blinds over all the windows. The battery compartment isn't 100% necessary right now as long as the cable compartment that's currently there for the moment though it has to be replaced. The priority is to get the above completed and get the retitling process under way. Longer term plans - well, the sky's the limit!
