Hello,
There are several types of 'chassis', or I'd rather say 'bodies' delivered to the builders.
Cabinato is one of them, so was also mine. It has a cab with no rear wall (roof is another option, mine had a H1 roof), it's covered with some kind of plastic protection same as the ones on the photos posted by AndyRKett (I've saw once it was called Aquilux, it has a structure of a cardboard, but is in plastic). But it also has a chassis + rear axis. As on the photo posted by Esban in his third post.
I've also seen chassis + engine + partial cab interior, but no body at all
That looks strange
(steering wheel but no seat
)
Most of the deliveries to the builders I've seen online were white. But I'm not 100% sure that the grey / blue campers/motorhomes were resprayed by the builders. Perhaps some 10+ years ago all were white, then the builders started to change the orders, as the customers were fed up by the white... And still, most of the commercial vans remain white.
17Q doesn't mean 1700 kg. It means 3500 kgs.
Mine is also 17Q:
CAPACITY PORTATA COMM. QLI = 35 QLI P.T.T (QLI17)
I was using this site to decode the VIN:
Spar parts catalog :: Allowing you to browse all the components of your vehicle online, without needing to make a trip to your local dealer shop.
www.pekidi.com
And it was quite close (or the closest one) to what I was said by the FIAT Pro dealer. The forum
ePER is further away (as it says for example 2 seats, and I know that both primary and secondary homologations of my van were made for 3 seats).
@Esban call the Stellantis hotline, they should be able to provide you the CoC, or the homologation extract.
