I know lightweight deckers are good initially but what about in 7 years time? GNE have stuck with heavyweight deckers (except the Angel) for the past 4 years now and nothing major has gone wrong with any of them. What you've got to remember also is that with no turbo on a Cummins Unit when it fails, the Horsepower would only be at roughly 150-200 bhp and that would cause problems. I've got nothing against Cummins engined vehicles but I don't like them for demanding work whatever the setup.
I think GNE would rather go for this option than have 7 more years of breakdowns with the B7s (or however long it may be) before a suitable heavyweight vehicle is out there...
