Thanks RJ!
The router guide is a great tip, I have a parallel fence new in the box that I should probably get acquainted with as burn in/ bearing life is a real shortfall of machining foam with a handheld router. I did run some smaller pieces through the router table which produced a nice finish in a easily controllable manner.
I find that the prep work for fiberglass takes almost as long as the actual layups. Making sure you have mixing supplies, pre-cut fiberglass cloth, peel ply, etc all ready to go makes layups go much smoother, but also consumes a lot of time.
This was the first time I used epoxy mixed with micro to bond panels together, although I typically start each layup with a small batch and fill any defects in the foam like router burn and the likes. I highly recommend it. It also did a great job bonding the panels together, but I wont be making that a common practice. The rest of my tub assembly is glued with pl-premium polyurethane construction adhesive and I'm quite satisfied with its performance. The pl premium has a much longer working time, which could be an advantage or a disadvantage, and its likely far cheaper per volume, although I haven't run the actual numbers. The micro is a great choice in instances where you need gap filling properties, like the gap created by the rocker in my floor panel. You can mix it to your desired stiffness by adding more or less micro. Cotton flock is also a thickening option, and is much stronger than micro. Ill be doing resin/flock fillets on all the inside corners prior to glassing the seams with 8" tape.
Im using Burt Rutan's Mold less composite sandwich aircraft construction manual as a guide. Most of the info is way overkill for a camper build, and I often have to tell myself that this is just a fancy tent, not an airplane or a boat. Its a great resource none the less. Here's a link to a .PDF if that sort of thing is allowed

The discussion here is really getting me to think about the build from other perspectives, and giving me some great ideas for upcoming aspects of the build. Thanks Fellas, more updates soon!
