Welcome to iRV2.
The ceiling height and roof support; are part of the overall coach structure ; aluminum trusses; you'd have to re-engineer the walls and raise the wall height to get more headroom.
You can drop the bathroom or fantastic vent trim and see what you're up against. With the HVAC and wiring that's up there in our roof trusses , it would be more cost effective to trade up to a coach with the headroom you want.
