Thanks for that! Looks very interesting but I could not help asking while reading 'What happens while reversing?' searched further and found a system from Knott

Soooo work is underway, have manages to dismantle all interior and all exterior all that remains are some mechanical parts and will start with the splitting. Am anxious to have it moving now!. Quick questiononor came without keys and fuel tank is locked shut. was thinking of drilling into lock. does it work or is there a better way to get it open.
