OK, we've made a start.
First we tidied up the load area a little and got rid of this

from here

all the rot cut out from one side. The remaining chassis was in really good condition. We've taken it back to bare metal and then given it a good coat of special primer - we then go on to do the same on the other side but i'm sure youget the picture

next we sorted out a couple of bits on the rear corner
that's it for now - plenty more to come on this one soon
