Yep I know all about BW7, and yep the GO would not store it at Hughes st (space was not the issue
). Sorry its stored at Monash & they drive it so I forgot it belongs to the whole of Chaffey
You can get all wheel drive tankers - the army had Mack 6x6 tankers no stability issues, however the Unimog 4x4 trial tankers were a shocker
(chained old F1 International bulk refueling equipment to them but the spring were to soft).
I don't think the Japanese chassis would carry a decent load cross country - need to be American special build
Anyway cheers
