hey bud, progress is looking good!
I'm in Calgary at the moment, with my bus up in edmonton while im sorting my way through the insurance hassles to drive it home. Theres another guy i met this week whos also in the build process at a similar stage as yours is in the pictures. I'm a bit behind you, just stripped it back so far.
The other guy suggested some 55 gallon drums on FB marketplace... ill send you the link when I find it
