Moving along nicely....
Attached floor pack to the frame.....
Placed windows and door for checking fit....
installed Rmax 1" rigid insulation between studs using reflectix tape...
More gratuitous pics....
Really happy with how this has come along so far. Just for piece of mind I used angle braces on each of the corners with tapping wafer head screws just for extra support on those integral parts. tomorrow I'm ordering the smooth aluminum siding from Mirage in Nampa ID. plan on using the VHB tape I just dropped $200.00 on and then will fab the roof frame and order an aluminum 1 piece for that. I will supplement the siding tape with a few well sealed skin screws as well. I also ordered and received all my internal and external lighting that I need to run wiring for. I also found this product
https://www.lowes.com/pd/FloorComfort-100-sq-ft-Premium-2mm-Flooring-Underlayment/50402206 that I will layer the entire inside of the camper with prior to siding it for extra spacing between the walls and panels to hopefully reduce condensation and thermal transfer. then the next steps will be mounting the jacks and ordering my Sail-Rite vinyl for the popup portion. Although, I might work on finishing the interior prior to completing the popup and roof for ease of working space. I opted for a 47 qt. rotomold cooler that I purchased instead of a refrigerator, less battery draw and with dry ice will work for any of my fishing trips as I'm usually near a town to replenish any ice and food.
I also am purchasing a suburban forced air furnace instead of any cat heater as I have gone back and forth between the 2 but opted for the furnace since I would feel 100% at ease running it while sleeping and it doesn't produce water vapor as minimal as it might be.
The only real concern I still have structurally is whe cabover portion. While I have aluminum angle around all 3 sides and then the frame itself to support to plywood sheeting for the bed I am concerned about that supporting my 250lbs sleeping on it. I will for sure screw it down and trust my welds but some other way to help support it would be nice, but maybe this is just how they are normally constructed. I haven't seen any of the ATC or FWC have any cross members underneath the bed in any of the research I have done.
Thats all for now, will update when the siding goes on!
