Attaching the 15 gallon drums underneath the bus was intended to be accomplished tomorrow. That won't be happening tomorrow though. Today I took m'lady to meet some friends of mine and during an exchange of information, I found why one of my previous positions ended. It transpired that I had not done the rotten job that I had been told I had done. It turned out that the manager in charge of the department quietly disliked me. That explains why some of the training I'd been give was rather obtuse. Afterwards, she'd admitted she'd got rid of me because she didn't like me. Now that I find is rather unusual because most people (not all) do seem to like me (or if they don't, they hide it pretty well).
So, the upshot of today is that I was in Lowes (hiss, spit) on the way back. My idea had been to use a chain with a turnbuckle to tighten it to perfection. That, it seems, is not possible. Looking at Lowes (hiss, spit) turnbuckles, they were all adorned with labels along the lines of "will not support a human" and "do not use to support weight" and seemed to be made of zinc. How useless is that? I have seen people using chains to secure tanks under their vehicles and I'm pretty sure they use turnbuckles to tighten their chains. Now it could be that Lowes (hiss, spit) specialises in supplying an inferior and inherently dangerous product and that many people just don't read the labels, ripping them off and relying upon them.
I had been criticised for considering using nylon cargo straps to secure my drums. It seems that cargo straps are probably the best idea. They can be tightened easily and while not being allegedly very durable, are probably as durable as a plastic tank! So, the answer is to put nylon cargo straps. While I don't possess cargo straps right now, they're easily obtainable. They're better doubled up for strength. I know 15 gallons of water weighs just over 125lbs. Thus if the cargo straps individually hold 120lbs then I can put 3 or 4 straps giving either one or two redundancies for safety.
While I Lowes (hiss, spit) I obtained some small wire nuts. I came to the conclusion that I'm better off replacing the top flashers with plain metal sheeting. The idea of turning them into extra turn and brake lights at the back is very worthy but in terms of practicality, means adding more complications. Thinking about the existing wiring, it seems to me that since it goes straight to the control panel, it could be linked to my small solar panel to use to keep the bus battery topped up. Indeed, it might even be possible to use the wires to connect a solar panel to charge the house battery. The house battery, by the way, only needs to hold enough power to charge my tablet and my phone. That's next to nothing! Certainly keeping the bus battery charged is a good idea. With a little care, the power could be redirected to power a small electric extraction fan at the back of the bus. That would give the option of using the power for the fan.
Another interesting idea would be to couple a small 12v battery into the charging circuit for the bus so the battery charges when the bus is driving or when solar power is going in but doesn't deplete the main batteries when it's being used to power the house circuits. Realistically, the simplest way of achieving this is with a simple switch on the driving console. Power goes into the house battery when the switch is on. When it's off, the circuits are separate though remembering to activate the switch might be an issue!
Tomorrow, I'm not sure which tasks I will undertake. I'll probably replace the worthless paper blinds though. I might then look at the front flashers or even take the bull by the horns and install the main breaker box.
