Small-fleet trailer reference table: usable dimensions, cargo weight and pallet spots for six US equipment types

A one-page CSV that a small trucking desk can keep open while it quotes. Each row gives rough working numbers for one equipment type used by one-to-five-truck carriers in the US: usable length, inside width, loading height, cargo weight and the number of 48x40 pallets that fit single-stacked. Covered: 26-ft straight box truck, 53-ft dry van, 53-ft reefer, 48-ft flatbed, 53-ft step deck and 40-ft hotshot gooseneck. These are planning figures, not manufacturer specs. Check the real unit's door opening, tare weight and axle ratings before booking; bridge-formula and state limits still apply. Typical uses: checking whether a quote request fits the equipment at all, estimating whether a reefer load weighs out before it cubes out, and deciding when tall freight belongs on a lower deck. The table came out of the notes our desk keeps on how we match tall freight to step decks.
