PS - if ‘Nippy Nigel’ is a visitor to this forum, I’d love to hear more about the above unit (engine, gearbox, work type…). Robert
An unusual 8-legger rigid sleeper here. I think NZ-Jamie posted these on the scrapbook thread a while back. Robert
Not my pic Bert mate,but I have seen it before and do have photos of it.
It was very tidy when I saw it I 2007,it was for sale not long after that,but I’ve no idea what happened to it.
It amazes me, Robert, that you keep coming up with new pictures of these excellent vehicles. Must have been a lot more built than I realised.

Well, at the rapid rate at which they rusted, they needed to produce a lot just to stand still!

A nice observation from over the water! 
And I love that livery too. Robert
The day-cab version of the metal cab was usually the MV cab, as shown below…
However, THIS picture appears to show a day-cab version of the 5MW (a contradiction in terms it would seem, as the letter ‘w’ denoted sleeper-cab). Perhaps it was a cut down 5MW, or more likely, an MV with a 5MW front - who knows!? Robert

The first one is a 3MV, the second a 5MV, by my reckoning.

Yes, that works! Robert
Hiya…Robert …

Hiya…Robert …that 6 legger looks like a narrow cab to me making it a MV. we need to see the roof panel to know
that it has a 9 inch panel welded in to widen the cab.i think its a short door MV…with the wings been painted black
as well as the step panel you can t see how wide the mudguards are…i have seen a photo of it been delivered somewhere
but can t remember…if you look at the photo with the dump truck on its easy to see the mudguard

Sorry John! I’ve just noticed it was not a 5MW cab - it looks like a 4MW to me - so I deleted it, and now I’ve just seen your post! robert 
The 6 wheeler above is definitely a 5MW day cab. The W does not denote a sleeper cab (where did that come from??).
The MV and MW are two entirely different cab structures, the MW being wider and taller as John says in his post. Hardly any panels are interchangeable. Note the gap from wheelarch up to the body swage line - it’s about 5 inches on an MW, but there is hardly any gap on an MV.
BOTH the MV and MV were available as a sleeper cab, the fact is that most MW’s were ordered as sleepers, and MV’s were mostly day cabs, but that is not their ‘set in stone’ spec.
I have the ERF master parts diagrams and lists for both cabs, and there were a plethora of different specs available for both cab types. Not least 4 options of windscreen in the MW.
The red and white MW in New Zealand with a Gardner 180 and Fuller RTO 915 gearbox from page 1 of this thread is now back here in the UK. This one is a 3MW cab from 1970 by the way, not a 5. It is thought to be the first one built to this spec, although the build records are still being checked to confirm.
ERF P-E-T-E-R-B-O-R-O-U-G-H…with all respect and awareness towards your expertise…
why did you input this important cab-information more earlier? Since more than a year we
are all strugling with details and the final answer.
It has been discussed numerous times, 3MV, 4MW, 5MW, 7MW and all derivations…
No doubt we appreciate your periodical posts and corrections but please bring your cards on
the table now! It would be nasty in case Robert releases incorrect info in his book.
Pitty that REVS was not actively aware or inputting on this as the sixties and seveties were
by far THE years of ERF! No hard feelings on you personally though
