Odyssey 4x4 Posted September 17, 2018 Share Posted September 17, 2018 I'm going to be pulling up and replacing the plywood flooring in the odyssey this week due to some soft wood. From what I see (going downward) it goes plywood, some type of styrofoam insulation board, and then a black mat to keep water or whatever out. My question is this, what is the insulation board? Is it something sold at home improvement stores? Is the black sheet part of the insulation board? Is the insulation board glued to the upper plywood sheet? Here is a pic where my plumbing went through and you can see the 3 layers... Quote Link to comment Share on other sites More sharing options...
linda s Posted September 17, 2018 Share Posted September 17, 2018 I'm betting it was all installed as a compressed sandwich. Makes all the layers stronger than they were before. Home Depot insulation board is fine but you need to beef up the plywood since you can't compress like a factory can Linda S Quote Link to comment Share on other sites More sharing options...
Odyssey 4x4 Posted September 17, 2018 Author Share Posted September 17, 2018 Maybe I can just spray adhesive on it and park a truck on the stacks for a few days! I try my hardest to not up the plywood size, as being tall makes my already low headroom precious. Quote Link to comment Share on other sites More sharing options...
linda s Posted September 17, 2018 Share Posted September 17, 2018 Definitely buy the best plywood you can. Marine grade is denser and stronger than the regular stuff. Linda S Quote Link to comment Share on other sites More sharing options...

linda s Posted September 17, 2018 Share Posted September 17, 2018 Some just call around. Your in florida. Bet they all have it. You need premium high ply when you ask. Costs more but worth It. Linda Quote Link to comment Share on other sites More sharing options...

Linda S That makes two of us. If I wasn't full time in classes and working I'd be cranking on that thing non stop everyday. The floor is ready to come out when I get it to my sisters steel building where it wont be exposed to the elements while I do the floor/walls/roof. I'm going to pull the floor out which should only take a few hours and then go through the frame and driveline under the truck, theres a bit of surface rust. Everything will be cleaned of rust, sprayed with a converter and painted. I'll pull the rear axle out of it and go through it on a bench. Leaf spring U-bolts need replacement as well as plates. I have the Bilsteins ready to go in and the current leafs on it are in great shape (a pack of 9 if I remember right). I'll go through the brakes as well as all the U-joints, seals, etc and that should finish up under the truck until I can afford the locker ?

linda s Posted September 18, 2018 Share Posted September 18, 2018 Make sure you know where the coach is attached to the frame. Floor might be a part of that and you don't want to dig too deep. I've never inspected an Odyssey so I don't know. Linda S Quote Link to comment Share on other sites More sharing options...
Odyssey 4x4 Posted September 19, 2018 Author Share Posted September 19, 2018 (edited) We made a decent dent on the floor today. It was a pretty big pain getting the generator box out! Turns out rusty old 28 year old screws aren't too fond of coming out. The rear window came out making removal of the refrigerator a breeze. We started with a drive to the shop, I'm always excited for an excuse to drive the rig. I knew this would be the last drive for a while until the camper shell work is complete. Rear window was out first (photos taken at the end of the day). Massive fridge OUT! The generator box was a hassle! We were then able to get the rear floor board completed removed after plenty of wrestling. The entire rear wall is completely rotted out. The wood was still wet and soggy. Don't you love when the seller says, "no leaks at all!" The remaining floor boards will be removed on the next day of work and any floor water issues addressed in wooden subframe. New insulation and new plywood cut to size and laid. I will be cleaning and painting the upper of the frame while the floor is out since it will make the work much easier.
