We've been experimenting with phenolic in our epoxy to thicken it for a filler, and used it to fill some small voids and gaps in the side of our floor. First attempt, right after putting a base coat over the entire back, the filler tended to run, so I sanded it down smooth, and the second time we just filled, and used clear packing tape to hold it in. Seems to have worked!
We did this Saturday morning, and I'll wait until at least tomorrow evening before sanding. I feel a little tack, but am confident it comes from the tape, not the epoxy. The reason for the confidence is that we preceded adding the phenolic by putting some of the batch over a few portions of the top I wasn't satisfied with yet, and they're now hard. Mostly I feel really good how the rest of the top came out after sanding with 120, then 220 grit sand paper. Hopefully, the new stuff will sand down as well and will blend right in.
We'll add two or three more coats to the back and then sand it down. The phenolic makes it look ugly--wouldn't do it with a woody--but it should take the right kind of primer and paint and give us the look we want.
We sure are taking our time on the floor, but we are learning a lot about the characteristics of the epoxy, and I'm confident now we'll have little trouble when we use it with fiber glass on the sides and later the roof. However, we have wasted a lot mixing larger batches than we need, and may have to order more before this is through. I've heard experienced folks save small tasks for those left over batches, and no doubt we'll start looking for things like that to do.
We don't plan to build out the galley until after a few camping trips, but Shelly was looking for water bottles, and we found these
Just the size we want--2.5 gal--in the shape container we wanted. Should fit well to the left of the galley, to the right of the battery hatch.
We'll probably store pots and pans, or dry food, over the hatch.
We wanted two 2.5 gal bottles simply for ease of handling over one 5 gal bottle. We plan to keep 5 gallons in the galley, which should be fine for camps with a water supply. For dry camps, we can take more in the truck. I used 5 gallons in the galley for the weight and balance spread sheet.
Shelly was also shopping for a better portable propane stove than our Coleman. The Coleman goes from nothing to high in about an eighth of a turn, and getting it to simmer was an issue. Shelly found a Camp Chef with good reviews, but it's 23 inches wide--two inches wider than our galley counter. (The Coleman is only 21.25 inches wide, enough to fit with just a little hanging out, but still small enough to close the hatch.) I really didn't want to store the stove width-wise; just not an efficient use of space, so I asked her to keep looking. I even wondered if anyone had replaced the valves in the Coleman with something better. We didn't find that, but someone had taken them apart and wiped the grease. That makes them adjust easier, without so much back-lash. Worked for us too! So we'll try it camping and see if that isn't good enough.
And while on the subject of the galley, we are thinking about making our own cooler someday. (Using our regular camping cooler in the truck in the mean time.) The idea might be to use 1/8 inch Baltic birch for the inside and outside, and several inches of blue foam in the middle. We could make it a custom size to fit in the galley (to the right of the battery box). We would also like to have two drawers, one for the ice, with sodas, etc. and another for other cold storage. And we would like the entire unit to be movable, so we could put it in a bear box or truck when in those areas. should be some interesting engineering!

It would be a long trip pulling a camper. Their trips will have daily average speeds in the 90+ MPH. That is crazy to me. And the mosquitos are thick which is a motivator to keep you moving because you don't want to stop. 
Then I add up how much I've spent on camp stoves up till now and it's well over what one of these cost. And everything I've read is that these stoves will last a lifetime. And you can pass it down to your grandkids. And you can get rebuild parts.
