I've been plugging away and getting a lot of little detail things tidied up that I've been pushing off or overlooking for quite a while. I extended the propane line a little bit farther towards the tank to facilitate actually removing the tank. My original plan was to try and somehow shut off the valve and disconnect the flexible line before lowering the tank. I figured that would probably prove to be a pain in the butt. The flex line that I have is long enough to lower the tank all the way to the ground now that the hard line comes all the way up to the tank's space. I got it all soldered and leak-checked on the ground away from my hard work.
I'm short one pipe fitting, but the system is otherwise complete. I believe what I need is a 1/16 close nipple. None of the local stores carry pipe that small, but McMaster has it. I need to order it. I sorted the drawer for the grill and confirmed everything will work as intended. Shown here is the closed/stowed orientation:
Ignore my hand as it's doing what the missing pipe fitting will do once I receive it. With the drawer all the way out, we can simply attach the quick connect to the grill with no tools, like so:
Note: I eliminated Coleman's ~6" pipe between the grill connection and their regulator, but I retained the regulator. I felt their "extension" was unnecessary now that we're not using disposable tanks, but I'm sure the regulator is necessary. The disposable tank thread size is 1"-20 in case anyone wants to try this at home. There is an adapter available to convert it to common pipe thread sizes. You shouldn't have to look too hard.
You'll recall a while back I made up a panel/box/hold down sort of contraption for the battery. I made it fit and made sure the battery was held down securely. What I didn't do until just recently was make provisions in the panel for securing it to the frame. So I match-marked and drilled out the bolt holes and I painted the laminated steel panel to prevent rusting. I also painted the hold down brackets, same reason. I've used 3/8" hardware pretty much everywhere, so 3/8" washers on the hold down as well. But they were slightly too big to fit in the hold down channel, so I put some flats on them to fit:
Not at all exciting. But this gives you the idea of the sorts of things I've been working. Details that give nothing to show for all the time spent. You'll also recall that we put two sets of rock lights (one red and one white) under the trailer for a night light. They've been ready to go in for a while, but without an actual final home. I put this off because in a couple spots there wasn't actually a panel to secure them to, but also because it meant un-pinning and re-pinning all the connectors which kind of sucks. But in the end it was worth it I think. This is the view from the top:
And from the bottom:
I also used some of the "scrap" marine plywood to make up a couple of floor pieces where they were lacking (under the fridge, sink and grill). I laid all of the wiring harness back into place and spent a good deal of time making sure it was routed in such a way that there won't be any interference with any moving parts and all that. I secured it all in place with zip ties, which required putting a screw into all of the zip tie bases so when the sticky-back fails, it won't all fall down. I also spliced in an override switch for the reverse lights, so if we want light around camp at night we can use those, rather than having to install more lights. Once all of the wiring was back in place and secured, I hooked up one of the solar panels and set it out in the driveway to catch some sun. The battery charged to 100% full, everything tested out fully functional. In short, it's all good.
Next up, I need to shorten a few wires at the fuse block that are too long, and re-terminate them. Then I can put the bed support piece back in place and secure the wiring to its underside. I need to extend one side marker light by about a foot. Then I can put up a wall and start cutting it to the right size and shape and all that. I'm super excited for it to have a real profile, but also nervous as hell. I hope it goes quickly, but I want to take my time so I don't screw it up. I feel like we're finally actually coming down the home stretch now that all those little kinks are sorted. I'm probably the only one that feels this way but I feel like it was a TON of progress. There's just very little to show for it. Oh well, no one's reading this anyways.
