Thanks guys.

I'm enjoying how it's all coming together, too. and now that I've got the mattress in there, I can even crawl inside for a nap when I get frustrated and pretend the whole thing is done already... pretty dangerous, really.

Thanks for the advice KC. I went ahead and nixed the Fiberglass idea, and instead tried the COE smoothie mix that I saw in George's build thread. It seemed goopy and messy and fun, and it was, mostly. Though I found I couldn't get it quite as smooth as I'd like, and there were clear marks from the edge of the putty knife thing no matter how hard I tried. Still I figured, since it was partially spackle, I might try sanding the peaks with something high grit. At least the weave was completely filled!
... and that brings us to another episode of "what went wrong with Amanda's build today."
So, first, the smoothie mix, I imagine due to its being 1/3 primer, actually sunk down a fair bit while drying and has exposed a bit of the weave again, again making the edge where the underlying metal meets the underlying foam pretty obvious. I'm torn between going in for another run of the smoothie mix, or just letting it dry, giving it some gentle sanding, and painting it to draw attention away from the imperfections (per usual). Still deciding.
And then there's the electronics. Got it all connected, got excited, went into the cabin to look and see if the voltimeter was on aaaaaaand... nothing. Plugged it into shore power and got something! The converter cooling fan turned on for a moment, and then I went and looked in the cabin excited to see the voltimeter lit up. But again, nothing.
Then I tried the cabin vent fan, and it made a buzzing noise, but didn't start. BUT, that then turned on the voltimeter.
Ok, right, figured there was something wrong with that circuit. So got out my mattress heating pad and a USB cord for my phone to be able to test the other outlets. And discovered that it was as it thought: the one outlet that was on its own circuit did fine. The others, not so much. Some quick googling later and triggering traumatic memories of my least favorite section of high school science class, and I realized I'd wired up my circuits as serial, rather than parallel. So I've got to open it up and fix it, but I'm having a hard time getting my head around where I should connect what in order to get it to function right with the connectors I have and the wires in place. It's doable, I'm certain. Just will take a bit more thought.
And I'm really, really hoping that the problem with the vent fan is linked to it not getting enough power with the way it's currently wired. Really don't feel like pulling that out and replacing it, although with the way I've installed it, I don't think that'll be impossible to do without breaking everything... just tricky, and the great stuff in there might fight me a bit.
Then it was time to address the fact that the battery didn't seem to be doing what it was supposed to. Luckily, google helped allay my fears that one or both of the most expensive parts of my trailer (other than the base) were just inherently broken. Turns out I had missed out a fuse. There's one in there that's to protect against reverse polarity if you accidentally put it in wrong, but it needs one on the actual circuit it's connected to, too. So there's that. Got the fuse plugged in there and viola! It powers my wrongly-wired electrical system just as well as shore power.
Was also really hoping to get the pullout shelf for my cooler installed yesterday, but it didn't work out that way. I was able to get all the right bolts to connect the hinges to the L-brackets, and bolt the L-brackets through the floor for maximum cooler support. Even found that I had guesstimated what size L-brackets I needed more or less right, and the cooler should fit in the very tight space I have for it. I think.
Unfortunately, it became clear that the way the screws connecting the hinges to the plastic tray itself was not going to work. I was hoping I could just kind of fudge it, but the amount it was going to have to be forced into a right angle was starting to deform the hinges which seemed like not the greatest idea.
Now, someone with basic woodworking skills would probably be able to get some wood with the right angle to be flush with the angled-in sides of the tray. But we've already established that wood and I don't get along, and I'd like more practice with fiberglass, so I decided to go that route instead.
In all, I did three thick layers of fiberglass last night, letting them dry in between, and I'm hoping that it fills in that gap enough to let me get some screws in there at a right angle. But it's a setback, since I'm here waiting for it to cure completely, before I go forward with that. Always more delays!
So then I moved forward with canvassing the inside of the hatch. I removed some of the wood in the bottom that was getting in the way, and hopefully I did enough. Also scraped the glue off of the support blocks for the gas strut mounts, and got those in there. Only one of the screws that was only meant to temporarily hold the mount on the block got stripped out, so I had to drill it out. Of course. Still need to get some bolts all the way through before I can reattach the struts and try again, though, since it's been established that the glue on its own is just not enough, and while the interior canvas may make somewhat of a difference, I'm not confident that it would be enough, and I reeeeeally don't want to re-do these again. So through-bolts with washers it is.
Have almost gone through my second gallon of gripper. Have so little canvassing left to do, but unfortunately, it's just not doing to be enough. Welp.
Highlight of the night: I DID at least manage to remember to lay the magnet for the center of the hatch (for a light or a hook or whatever) before I canvassed it. And I think I even got it put in the right way! So hey, silver lining.
Still, even with the door sort of shoved in just to test fit it temporality, it's starting to feel like an interior space in there. And I think it's pretty much the perfect size for me, with a super comfy bed, and appropriate proportions.
Don't know if anyone's going to read all of that without pictures, but here's a TL;DR: Making progress. Slowly. Kind of. Things going wrong constantly. CANNOT WAIT to be done with this. Hopefully not long now.
