Ok, now here is an update.
There are no more seats in the bus, the floor painted rust-oleum and the insulation with a plywood delivered...
What i want to say... IT WAS F!@#$KING a lot of SH#TY work!))
I've read here that the seats removing is a pain in the ass, but it is nothing compare to rubber floor removing!!
half of a screws just got broken the moment you start to unscrew them!
So in the end in most cases i just force-pulled them out)
The rubber is sticked with glue to the floor and sometimes it takes a lot of scratch-work to remove it.
Anyway... we did it))) And tomorrow will be maintaining new floor with deadening sound subfloor..
I'll show you what it will be.
P.S. Still looking for insurance that will insure our DreamBus and will be grateful for the help
