So back when I bought by bus my dad and I had run a saw through the entire length of the floor board expecting there to be a solid metal floor below it... we we're wrong. We lifted up the board and saw the driveway below it! So we decided it would be best to replace the middle floor boards so we know we are building on a solid base.
So here is the process it took to replace the floor we had ripped up and also re create a floor near the cab of the bus. Thanks for following along on the journey!
