hi todd,
i can only answer the question about the floor thickness for my 1990.
i have one picture below that shows the thickness at the door entrance steps, but it is a little misleading.
i will try to describe it.
picture the steel frame of the newell BEFORE they put any floor decking on. from each side (drivers, passenger) there was a steel sheet from the outside edge coming in about 3 feet.
then on top of that all the way across the newell was a sheet of 1/2" plywood. on top of that was strips of the 1/2" plywood about 2" wide and 2 pieces high that were stapled together forming a riser or firring strip that were put down on the floor like studs would be put up forming a wall.
in between those strips was 1" high density sytrofoam insulation that was cut from a sheet.
then on top of that was another layer of 1/2" plywood. in areas that needed extra strength or support it was 4 layers of 1/2" plywood. then they put sheet linoleum on top of the floor everywhere. where there were tile floors in the 90, they put it directly on top of the linoleum. when i put granite down i put an antifracture membrane that ernie recommended and it worked great.
btw, on those coaches with air grills in the floor up at the passenger or drivers seat, newell used the channel between the upper and lower sheets of 1/2" plywood as air ducts by not putting insulation in betwen the strips of wood and making sure the strips of wood channeled the air to the plenum for the dash air and heat so you could recirculate inside the coach (like max air) in your car for the dash air/heat system.
the passenger and drivers seat did not have 4 layers of plywood underneath them so when i had the seats out i had to replace some of that wood anyway so i made it a full 2" directly under the seat mounting bolts, but the bolts also went all the way through the bottom of the coach floor so you had to get underneath the newell to take the nuts off.
hope that helps. if someone has experiences with the floors in the 80's coaches, please chime in. i suspect they were they same as i doubt they changed their floor design by going from one body style to another.
later
