@eLMeR> Thank you for this detailed answer 
, thus not to be wrong, it is all necessary to rename them "1990-1995 Utilimaster Aeromaster" by deleting Chassis-Code ?
, thus not to be wrong, it is all necessary to rename them "1990-1995 Utilimaster Aeromaster" by deleting Chassis-Code ?The vehicle rented by cinemavehicles.com is partially wrongly identified: this van is clearly a 1990-95 Utilimaster Aeromaster. It apparently just uses a GM P-Series chassis, which can't be identified from outside (Ford chassis were also a possibility for this generation). For me, it's another proof that these sites should just be seen as an aid in identifying the vehicles, not as an irrefutable source.
All vehicles identified in the IMCDb pages you listed are Utilimaster Aeromasters. This said, the P-30 model code, when added, is disturbing as it suggests that the concerned van is based on a GM 1-ton chassis (hard to be sure of it, for me). But depending on the chassis make, it should then be a P-30 (Chevrolet version) or a P-3500 (GMC one). And these vans are now referred to as Aeromaster 33 (without the P prefix) in Utilimaster's literature, not as P-30.
The other chassis supplier don't/didn't use such a model code either:
• The 1996+ Aeromaster 30 is based on the International 1652 chassis;
• the 1999+ Aeromaster 33 is based on the Workhorse P-3 chassis (which was formerly the GM P-30/P-3500 one);
• The 1996+ Aeromaster 36 is based on Ford E250, E350 or E450 models (1990-95 basis and model name to be identified);
• The Aeromaster 31 / 32 / 35 (1996-2002) and 39 / 40 / 41 (2002+) are based on Freightliner MT-35 to MT-55 chassis.
(All details were found in the concerned part catalogs)
I assume that the P-30 model code was once added for a Chevrolet based model and later mistakenly added for some other vans... In my opinion, this model identification, if accurate, shouldn't be used as model code. But some old habits take time to disappear
For the record, step van is another generic name for the walk-in vans. But it's also the sales name used by Chevrolet (with a hyphen and P-10, P-20 and P-30 sub-models) while the GMC sibling was sold as Value Van (P-1500, P-2500 and P-3500):
