01 What makes it unique
Aliner lists the 2026 Classic Rear Sofa/Mattress at 1,725 lb dry, a GVWR of 3,000 lb and a tongue weight of 160 lb. Aliner prints no cargo carrying capacity for it, so none is given here; the federal label inside the trailer carries one.
It is 15' long and 64" high folded for travel. Aliner prints its tanks as 11 gal fresh.
Among the 13 models Aliner lists for 2026 with a published dry weight, it is number 5 from the lightest, in a range from 1,190 lb (Scout Lite) to 2,600 lb (Aliner Amp). Every figure in that comparison is Aliner’s, for the same model year.
Every number on this page was read on 5 Nov 2026 from Aliner’s 2026 Product Catalog, the maker’s own dated document for model year 2026.

04 Notes on this floorplan
What Aliner does not publish for the Classic Rear Sofa/Mattress
Aliner prints no cargo carrying capacity, 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.

11 NHTSA safety record
NHTSA holds 3 recall campaigns and 5 owner complaints (model years 2005 on) against the Aliner line (a recall and a complaint are not the same thing).
Too few reports to show a pattern. 5 complaints have been filed on this line — not enough to say what fails most often. They cover structure and suspension.
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 Aliner line page.
