Flipping it onto it's back and removing some rubber matting I was presented with this:
|Rotten Chipboard at its best!|
The was only one thing for it. It had to be removed, so out came the jigsaw and hand saw and below is where things currently stand.
|Most of the rotten chipboard is gone|
I still have more wood to chop away from the left side, I think I will probably make a complete new base section and fix it onto what remains of the existing cab.
