my goal, once I find my bus, is to make a comfortable unit, reasonably attractive, and very practical for my needs, using methods that will allow me to complete the conversion while I can still use it - lol

OMG! Don't try this at (Tiny) Home, kids!!!

I conscripted my bus as The Kwik-Exit Moving Company, to get the frell outta Dodge.
All mods are taking place while I am in residence.
This whole evolution would go multiple orders of magnitude more quickly; if I didn't have to keep relocating crap, working around my built-ins, going extra steps to minimize metal shavings contamination, et al.
'Course, you have a home base for all of your stuff, so you needn't have a diesel blivet like me...

Okay, we can close this thread. You all come up with some amazing solution, none of which fit my criteria. Once the WHOLE ceiling is glued I imagine it will have as much or close to the strength it had before. I don't think there is enough flex in a bus to pull it all apart. My plan was to widen the groove on the first piece going up against the underlayment and tucking the underlayment into the groove. But both boards are 1/4" thick, so I will remove the bottom of the groove edge, overlap it on the underlayment. I'm going to go ahead and glue up a sample and see how hard it is to pull off after curing.

What I'm seeing is no one has done it so it's all speculation.

I'll be able to park my bus 25' from my house, and 15' from my workshop, so that should help - I don't envy you living in the construction zone, or those that have to drive to where their bus is parked, or worse yet, having to rent a space to work on their bus - I have virtually no worries about vandalism with my mobile security team in place, plus living so far off the road -

I had 3 construction adhesives to choose from, so was going to do 3 separate boards to see which worked best. I put the first one up, Dynaflex Ultra. Started to glue up the second one and the first one fell down, so much for grabbing ability, stuck it back up there. Proceeded to stick the second one up, Loctite Power Grab HD, 0 second instant grab, seemed to work. The first one fell down again. That's when I realized it isn't adhesive, it's sealer caulk, duh.
The 3rd one went up with Loctite PL Max Premium. I'll hang from both tomorrow and see if they hold my weight (162, down from 21

l'll be watching to see which glue holds best - now you know that caulking doesn't work the same as glue - lol

I knew that before, just didn't read the label to know it wasn't adhesive.
I'm guessing I won't know which holds better as they will both probably hold my weight.

if either one will hold your weight, then either one would hold an 1/8" thick panel in place I would think

[HazMatt]

Nice! That setup will make things considerably easier.
My commute isn't at all painful- open my eyes in the AM, & I'm there...
"Mobile Security Team," LOVE it!

ROFL Yet another tragic tale of caulk self-abuse!
Can you wedge the planks against their sealing surface using C-clamps against the hat-channels?

1/4", but all it needs to do is hold them in place.

[Sleddgracer]

"Can you wedge the planks against their sealing surface using C-clamps against the hat-channels?"

good idea - with a bit of a modification, that idea might just work fine - using a 2x4 to wedge the panel up, and C clamp the 2x4 to the hat channel should keep the panel damage free

I'm thinking of 1/8" thick pre-finished paneling with one of the photo finishes they offer

[o1marc]

I looked at birch 1/4" ply, $45, then saw this 1/4" underlayment and thought it would be like crappy OSB or something. It actually can be used as a finished surface. The grain pattern is good and has unique Pine Beetle bore holes that effected the color around the bore hole, then each perfect 3/16" bore hole was filled with light colored filler. I think it has lots of character. $14/sheet. Think it will take stain nicely also.

very nice find ! - it is going to take a fair bit of sanding to get rid of the cross hatch marks - they'll grab all the attention when finished with a clear stain

[o1marc]

2.5 hours after putting these 2 test pieces up. I'm good with either LocTite product for this application. Now I get the sawzall to cut those samples down.
Here's 100lbs hanging from them.

[superbusWI]

very nice flooring bro! looks sharp as a tack

[HazMatt]

Like a homely broad, it has LOTSA character!
Dissimilarly, you might want to run to moderately coarse sandpaper, to knock down the mill marks before finishing the sheets.
Is that going over the wall/ceiling curve? 1/8" plywood is plenty bitch-kitty to fit. Kerfs, maybe 1/4" spacing, might make it go. More easily, anyhoo...

What will that poor child do after being cut off at the wrists..?

The 1/4" ply will span the center section of the ceiling down the 2 fore and aft rails, the boards will start from that rail and continue down the ceiling to the tops of the windows.
Here's my 165lbs hanging.

[o1marc]

I have made curved "T" braces to push the ply against the ceiling while it sets. Don't think I'll need anything to hold the boards other than the 0 second grip adhesive. Gotta run the electric in the garage tomorrow and then panel the ceiling.
