KF-B "Hole" Middling Chassis
KF-B "Hole" Middling Chassis gives you an 18-cell 4x3 Middling frame, so it is the chassis to compare when a build wants width for side-by-side guns, cargo, and repair space.
KF-L "Hole" Middling Chassis gives you an 18-cell 3x4 Middling frame, so it is the chassis to check when a build wants more length than the wider Hole variant.
KF-L "Hole" Middling Chassis feels better when a Middling build wants a longer interior instead of a wider one. Its 3x4 grid still gives 18 cells, but the shape leans toward front-to-back room planning rather than broad side-by-side placement. That usually feels cleaner for cargo, support, and movement lanes while still staying short of Great-tier cost and scale.
It is one of the Trampler chassis options selected in the Trampler Editor before you place compartments and weapons.
KF-B "Hole" Middling Chassis gives you an 18-cell 4x3 Middling frame, so it is the chassis to compare when a build wants width for side-by-side guns, cargo, and repair space.
KF-B "Trench" Great Chassis gives you a 22-cell 5x3 Great frame, so it makes sense when the build wants a long hull for cargo lines, gun rooms, and interior lanes.
KF-L "Abyss" Royal Chassis gives you a 32-cell 4x6 Royal frame, so it is the long late-game hull to compare when one Trampler must carry cargo, crew space, and heavy systems together.
KF-L "Trench" Great Chassis gives you a 22-cell 3x5 Great frame, so it is the long-hull Great option for players who want more depth than the wider Trench layout.
KF-Q "Abyss" Royal Chassis gives you a 30-cell 5x5 Royal frame, so it is the square late-game hull to compare when the build wants a balanced center instead of a long ship.
KF-Q "Trench" Great Chassis gives you a 20-cell 4x4 Great frame, so it is the squarer Great option when the build wants a compact center more than raw cell count.
KF-Q "Well" Small Chassis gives you a 16-cell 3x3 Small frame, so it is the tight starter hull to use when the build needs a compact square Trampler instead of cargo-heavy space.
S&H Atm.Fs 77B-L Small Chassis starts making sense when a compact Trampler still leaves enough room for cargo, guns, repairs, and movement.
The longer 3x4 shape is easier to live with when movement, storage, and support rooms need to run front to back.
The tradeoff is width. A 3x4 layout helps room sequencing, but it gives less side-by-side flexibility than the 4x3 Middling alternative.
Yes, when you want an 18-cell Middling chassis with a longer 3x4 footprint instead of a wider 4x3 one.
The 3x4 grid is the main difference. It keeps the same 18 cells as the other Hole Middling chassis but changes how the rooms line up.
