Dodge D60 - or not?

[serge]

Hello

About the kind of DODGE some own one speed rear axle and other two speeds rear axle.

DODGE D60 L4 : long wheel base , dual wheels at the rear with two speeds at rear axle and special body with steel storage. Side of body made of steel.

DODGE D60 L5 long wheel base , single wheel at the rear and always two speeds and common body.

DODGE D60 L9 : long wheel base , dual wheels at the rear with single speed at raer axle and common body.

DODGE D60 L12 long wheel base ,dual wheels at the rear with two speeds at rear axle and common body

DODGE D60 L14 long wheel base , dual rear wheels single speed at the rear but only for civilian use.

In any case fot L5, L9, L12 there was three kinds of body : steel body, and two kinds of composite body (wood and steel

My only question is about short wheel base . All of them own a DUMP and all trucks I saw belonged two speeds rear axle bit but some have single wheel at the rear axle and other two wheels. DODGE D60 L13 for DODGE with two rear wheels biut what denimination the the dump with single rear wheel?????
