Its now down to bare wood and all looks solid with no soft spots so i am now ready for replacing the carpet with lino vinyl this will be easy to keep clean when spending nights on muddy campsites
While i had the carpet out i cleaned all the floor air vents and the vents for the fridge
while i was messing taking the units out i inspected the 240v wiring and not very happy with it so i am going to rewire the full lot
