Generally speaking, what are people doing with their fiberglass shuttle buses lighting wise and what do we have to work with in regards to the ceilings. Like how much recessed room can i anticipate is up there underneath the stock fabric ceiling? I can provide pics later, its just some fabric ceiling. I want to either install my own (plywood backing and sheet rock) or cut holes in what's already there so I can install recessed led lights. Either way, I forsee ceiling work in my future

I would not install sheetrock on the ceiling of any moving vehicle. Now if you plan to park the rig permanently then that is another thing. The continuous vibration will eventually bring the sheetrock down on your head. It's way too heavy and only supported by the paper on either side of the sheetrock. Typically you would use firing strips, insolation of some kind, and thin lightweight plywood like 1/4 inch Luan or Birch. You could even put in enough firing strips to use shiplap in rustic pine or tongue & groove cedar planks.

Please don't use sheetrock. Try something like thin wood panel or frp board. Anything light, flexible, and durable. Some have had good luck with those corrugated plastic sheets, like what political signs are made of.

If I were to do this for myself, here's what I'd do.
1. Totally clean the ceiling.
2. Cut 1/2" expanded polystyrene board into into 6" to 8" squares, then "tile" the ceiling with them, using construction adhesive. The squares would make it easier to fit the curvature of the ceiling, and be light enough for the tackiness of the adhesive to hold them up until it sets. Some pieces would need to be smaller to fit the tighter curves at the edges. Let the adhesive set up before proceeding to the next step.
3. Repeat step 2, overlapping the new squares over the joints in the previous squares.
4. Repeat step 3
5. Repeat step 4
6. Attach lath strips, running lengthwise to the ceiling, about a foot to 16" apart, to the foam board with construction adhesive and nuts & bolts through the fiberglass roof.
7. Get up on the roof and seal all the bolts with RV roof sealant
8. Run all the wiring
9. Cover the insulation, lath and wiring with 1/8" plywood, screwed and glued to the lath
10. Cut holes for the recessed lighting
11. Paint the plywood
12. Install the lights
