Rubbish you brought this thread up just to take the heat off your "holiday thread"
However to anwser your question, 18 months on, no its an ideal size to hold all the bits, 4 batteries, fridge/freezer (I joke not) etc. Think Tue will find the same with his new console. Windscreen to follow this winter after a week up in Oban looking at Puffin Divers ribs, (big 11m Redbays with huge console, screen and soft cover for the driver brilliant even at the expense of room for the divers).
Would I do anything differently, yes the wiring, each wire was labelled with sticky labels but they all fell off causing lots of grief as the wiring is all HD grey stuff. Chris and the FGT have shown now how it should be done, not how most of the builders do it unfortunately
would I do it again, well wonder what a P22 would look like with a cabin ?
