Hey Andrew,
You may be a bit young to know about the B model Mack, That was a gearbox combination to get your head around while driving on dirt roads with a load of logs on.

cheers for that
Must be a bad photo. The frame rails are not thin at all , in fact I would class it as a rigid chassis with really solid tube cross members.
I never put the verniers on it but I'd say it was 4 mm box section at least.
agreed- the rails arent very big, but quite thick. id say (offhand) 5, maybe even 6mm thick. looks lots more solid than previous canter chassis'.
spoke again to the WA iveco agent the other day, he said ADR had all gone though. they are looking at bringing models in for the 2013 market year, with a production run starting sept (i think?). the final GVM is at 5200kg, due to some braking issue for ADR. little bit of a dissapointment there for possible camper builds, but should still be ok.
XZLs are a 2.5k option, and something about speed limiting for the offroad tyres.. the XZL speed rating is 110, so thats probly what it is. believe me even 110km/h speed limiting is a major pain in the gregory peck when your trying to overtake a 50m long truck doing 105 itself...
