While doing research on types of flooring, I came across Altro Transflor Meta. It offers slip resistance in wet or dry situations. Comes in 6.5' wide rolls and sold for $30 per sq yd. Looking at the Storm color. https://www.altrofloors.com/Altro-Transflor-Meta
Got in contact with a "local" rep and discussed the color and pattern to lay it to minimize cost. I'm all about saving money.
Then in a conversation with a service guy at International Santex, He told me that to get the floor done there would cost about $7,000.00 YIKES! Any discounts for retired and military guys? Not really. BUT he does side jobs and if we purchased the material, only have to pay for his labor of removing the old floor, 4 benches and the lift. Then clean and patch the metal before laying new plywood and the Transflor with non PVC reacting adhesive. Then reinstalling the lift and wheelchair tie downs. Thinking of using lifting blocks on two of the bench seats and installing longer seat belts so it will be better suited for adult use.
The plywood is $38 per 4x8 sheet and I would need 6. Non pressure treated is $10 cheaper. Perhaps I can talk the International guy into removing and sealing up the roof escape hatches with sheet metal.
Not in any hurry to get this done as I am still wanting to get the transmission upgraded to a MT643 and get a lower ratio rear diff. Took a short trip and ended up getting about 8 MPG. A bit of stop n go traffic but mostly I was cruisin at 55-60 MPH with the engine at 2900 RPM.
