I drilled out the rivets that held the composite wood floor to the van floor and pulled out the two piece floor. The floor is dirty and needs to be degreased but I plan on using the floor again. I will add insulation and sound deadening material to the floor, walls and ceiling of the van. I’ve been perusing the internet looking for some insulation tips and a place to purchase good inexpensive materials. I found a report from a Western Washington University student who did a scientific test on what type of insulation to use on a bus project (the report is on the EZ cool website). The van really needs some sound deadening material but it is already significantly quieter since I removed the metal racks and the and the passenger compartment metal separating panel.
