Scale dimensions for a reefer/curtainside

[Snowman]

Hey guys, was wondering if anyone could tell me if I was to build a reefer or curtainside trailer, how long should I make it to replicate the most common size in scale 1/1. Don't have a clue on how long a standard reefer or curtainside is in the US as I live across the pond.
Any help much appreciated!
