Today I tackled DIYB ( do it yourself bodgery ) I repaced the floor or rather started with bits of plywood I had left over from our renault camper. Was going to use it for model railway but not wanting to go through floor I took the old out and slowly replaced with the new and some old wood screws I found lying around and bits of other wood. Took a while as outside temp was 86f at one point. I am not a diy chap so approached it with belt and braces approach but at leat what I done works so far
