Filters apply to the currently published quarter only. Work manufacturer -> line or model -> year -> dimensions so you do not orphan a narrow choice that has no rows.
If results suddenly clear after one change, that value may be incompatible with other selections (for example berth count vs layout). Remove the last filter or use reset controls.
Manufacturer and model lists depend on upstream data - typos in source feeds can hide expected names; try partial matches or alternate spellings.
Table and grid views read the same data. On small screens, horizontal scroll or switch layouts for readability.
Save or note the quarter string when sharing a valuation with a customer so they can reproduce it later.
Using the guide search effectively
Cascade filters deliberately; reset when results disappear; table vs grid is presentation only.
