Every number on this page was read on 6 Nov 2026 from Gulf Stream’s own Conquest model pages on gulfstreamcoach.com (no model year stated) for the Conquest 408TBS, which names no model year; the figures are shown as the maker published them, and no year is claimed for them.

- Gulf Stream prints "Dry Weight", "Hitch Weight" and "Net Carrying Capacity" on this page with no unit on the figures (its own line listing states weights in lbs.; tank figures carry no unit). No GVWR is printed, so nothing is checked against one. Page footnote: "Specifications are approximate and subject to change. Check the label in your unit for actual weights and capacities."

What Gulf Stream does not publish for the Conquest 408TBS
Gulf Stream prints no GVWR, tire size, grey-tank, black-tank, sleeping capacity for this model, so none is given. Nothing is filled from a sibling model, a different model year or a dealer listing.
Read the label on the trailer
Federal rules put a load-carrying label inside every RV trailer: its unloaded weight with full propane, its cargo carrying capacity and its GVWR (49 CFR 571.110 and 571.120). Those figures come from the trailer itself and govern the towing decision.
