Bachmann's Sidedoor caboose gives 55n3 a valuble piece of rolling stock.
The only distraction is the floor doesn't match up with the door sill. That is made up for in realistic lighting and full interior.
The Bachmann 55n3 Sidedoor Caboose matches well with their 55n3 4-4-0.
The Caboose matches well with Bachmann's On30 freight cars modified to 55n3.
