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 "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-L "Trench" Great Chassis feels best in builds that want length first. Its 3x5 grid still gives 22 cells, but the shape pulls the Trampler toward long interior lanes instead of a broad middle section. That usually works better when cargo, crew movement, and support rooms need to flow front to back without stepping up to a Royal chassis.
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 "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-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.
That 3x5 hull feels smoother when the layout needs movement lanes, support space, and rear cargo in one long run.
The cost of that long shape is width. If your Great build wants a squarer combat core or side-by-side room blocks, another chassis fits better.
Yes, when you want a Great chassis with a longer 3x5 footprint and 22 cells for a stretched interior layout.
The 3x5 grid is the deciding fact. It keeps 22 cells, but spends them on length rather than width.
