While I was in the bus, I sat down and completed my second 20A cable. The one terminates in a NEMA 6-30R which will plug straight into the NEMA 6-30C when the battery compartment is completed. Construction in failing light was not easy but was completed fairly swiftly. I have to say it doesn't look at all bad. It was confusing that the hot/cold pins had no markings other than X and Y which meant I had to look it up to see which wire should go where. I'll doubtless get the same issue when I wire the NEMA 6-30C.
When I went out I planned to stop off at a place where barrels were on sale. Oops... I was in thick traffic and missed the turning so I carried on to Lowes (hiss, spit). There, I realised I'd forgotten the piece of tubing I'd cut to take to Lowes for sizing! Still, I had a look at various plumbing bits. Then I looked at hooks from which I could hang my bucket. Looking at them, they would have had a difficult job coping with the lip inside the skirt on the bus. I passed on buying a hook. That was fortunate as it so happened.
On the way back home, I passed the sign where used barrels were on offer. The actual place was a long way down a lane. Down the end of the lane was a downtrodden looking mobile home. In the yard, a big dog barked noisily while some 15 gallon barrels stood to attention. The fellow must have seen me arrive and opened the door as I approached. He was very pleasant and didn't have change for my $20 so rather then buying two of his $8 apiece 15 gallon drums, I bought 3 with my $24. They had contained some kind of brownish liquid wax. That was slopping about inside the drums so I made very sure the caps were screwed on firmly in order to avoid spills. Clearly the fellow worked where such barrels were used. I'm very happy with my barrels. I suppose I could put 3 grey water tanks or two grey and a black just in case I decide to put a flush toilet some day.
Looking around the bus today, I noticed a tag from a conversion company. I've never noticed it before but it looks like it was Tennessee hillbillies that did the conversion. Clearly some kind of professional hillbilly conversion.
