It is a Dominant (early model... still learning/researching specifics), The bus finished its commercial life in VIC (Australia) bought at action... I am still tracking down info from a motor home club about the person who bought it (at the action) or when I travel to vic I will try to track down the action - only hitting dead ends so far butt I am particularly interested to find out the history of my home.

Note my Isuzu is turbo charged (/T some where in it name - the above spec are for the naturally aspirated) and it was ordered/built with this engine instead of a 466... the most popular choice 4 people who choose to swap their 466 (instead of rebuild) for an Isuzu is the 6BD2 (T)...
Conversion requirements are basic... new engine mounts... re size/balance tail shaft if you go for the longer 7sp gear box and/or get the engine mounts wrong... remount (and or replace) radiator... jump through legal hoops for engineer certificates *** you need to chase up the detail requirements for engineer cert first, the engineer will typically require a licensed welder and specific high tensile bolts, steal types, steal thicknesses etc - you may find it MUCH easier to get the engineer to fabricate the mounts (hence the need to do the tail shaft when they don't quite get it right)
