01 What makes it unique
Airstream lists the 2019 Sport 16RB at 2,860 lb unit base weight (with LP and batteries), a GVWR of 3,500 lb, a net carrying capacity of 640 lb and a tongue weight of 378 lb. Its unit base weight plus its net carrying capacity comes to exactly its GVWR.
It is 16 ft. 4 in. long and 9 ft. 3 in. high. Airstream prints its tanks as 23 gal fresh.
Among the 2 Sport floorplans Airstream’s 2019 Sport brochure lists with a published unit base weight, it is number 1 from the lightest by unit base weight, in a range from 2,860 lb (Sport 16RB) to 3,634 lb (Sport 22FB). Every figure in that comparison is Airstream’s, for the same model year.
Every number on this page was read on 7 Nov 2026 from Airstream’s 2019 Sport brochure, the maker’s own dated document for model year 2019.

Towing it
Check your vehicle. Enter the ratings from your owner’s manual and the door-pillar placard.
Compares your figures with this page’s published GVWR (3,500 lb) and the upper loaded tongue estimate (525 lb, a rule of thumb). Your vehicle’s placard and the trailer’s own weight label govern.
Loaded range: 10–15% of GVWR on the tongue, a rule of thumb, not a measurement of this unit. No truck ratings or hitch classes (why; NHTSA, DOT HS 809 433). The range starts at the published figure, because loaded is never lighter than that.

04 Notes on this floorplan
What Airstream does not publish for the Sport 16RB
Airstream prints no tire size, grey-tank, black-tank 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.
05 How it compares
3,634 lb unit base weight and 4,500 lb GVWR, against this model’s 2,860 lb and 3,500 lb.
06 Loading it for a trip
A full 23-gallon fresh tank is about 191 lb of water (water counts as cargo: 49 CFR 571.110 S9.3.2), 30% of the Sport 16RB’s 640 lb cargo capacity, leaving 449 lb (112 lb per rated berth). Your own unit’s figure is on the label inside its entry door (49 CFR 571.110 S9.3.3).

11 NHTSA safety record
NHTSA holds 7 recall campaigns and 1 owner complaint (model years 2005 on) against the Sport line (a recall and a complaint are not the same thing).
Too few reports to show a pattern. 1 complaint has been filed on this line — not enough to say what fails most often. It covers electrical system.
Recall coverage here is not complete, and complaints are owners’ unverified reports (how this record is built). Check a specific VIN at NHTSA before you buy. Full tables are on the Sport line page.
