As Antoine says 3 and 4 are definetly Sprinters, the 3rd being more accurate than the 4th but still,

The seventh is probabaly a Chevrolet COE? http://www.imcdb.org/vehicle_29525-Chevrolet-COE-1948.html

Eighth seems to be a Freightliner or White Freightliner, no?

Nineth seems to be a Chevrolet Avalanche or Cadillac Escalade.

Tenth could be a Mack?

The eleventh motorhome seem ot be a Fleetwood Storm or something like that http://www.imcdb.org/vehicle_29188-Fleetwood-Southwind-Storm-32-Y-1999.html

Thirteenth probabaly a Mack B-81 SX? http://www.imcdb.org/vehicle_15628-Mack-B-81-SX.html

Fourtennth id say it is a mack

The Fiveteenth fire engine seems to be a Mack MB Series http://www.imcdb.org/vehicle_38750-Mack-MBSeries-1986.html

Hope that was of help Steve.
