I hadn't seen that post Rigga as he is blocked, I concur, the system is more or less the same regardless of size and I have done aircraft a lot larger than a 172.
ZA150 was on the East African Airways fleet prior to conversion, as for stripping the refueling gear, you wouldn't really get that much out of it and you would still end up needing something to fit it too.. one wonders what the FAA will make of the slide as it was disabled in UK use.
