01 What makes it unique
Aliner lists the 2026 Evolution 12 at 1,965 lb dry, a GVWR of 3,000 lb and a tongue weight of 210 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 67" 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 8 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.
How the Evolution 12 differs from the other twelve Aliner floorplans. Most distinctive first. How these ranks are worked out.
- Tongue weight, 210 lb: fourth-heaviest of thirteen, between the 15 and Amp (200 lb) and the Evolution 15 Twin Bed, Expedition Rear Sofa/Mattress and LG (240 lb).
- Tongue weight as a share of dry weight, 10.7%: fourth-largest of thirteen, between the Evolution 15 Twin Bed and LG (10%) and the Lite (10.9%).
- Dry weight, 1,965 lb: sixth-heaviest of thirteen, between the LXE (1,930 lb) and the Expedition Rear Sofa/Mattress (1,985 lb).
- Length, 15 ft: shared with the Classic Rear Sofa/Mattress, Classic Twin Bed and three others; of thirteen, two shorter and five longer, nearest the Dinette and Lite (13 ft) and the 15, Amp and three others (18 ft).
- Interior height, 8 ft 1 in: shared with the Classic Rear Sofa/Mattress, Classic Twin Bed and three others; of thirteen, two lower and five taller, nearest the Dinette and Lite (7 ft) and the 15, Amp and three others (8 ft 3 in).
Next to the LXE, the nearest lighter floorplan by dry weight, the Evolution 12 is 35 lb heavier by dry weight and has a tongue weight 30 lb heavier; the two publish the same GVWR, length, interior height and fresh tank.
Next to the Expedition Rear Sofa/Mattress, the nearest heavier floorplan by dry weight, the Evolution 12 is 20 lb lighter by dry weight, has a GVWR 500 lb lower, has a tongue weight 30 lb lighter, is 3 ft shorter and has 2 in less interior height; the two publish the same fresh tank.

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 (3,000 lb) and the upper loaded tongue estimate (450 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).

04 Notes on this floorplan
What Aliner does not publish for the Evolution 12
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.
05 How it compares
1,930 lb dry and 3,000 lb GVWR, against this model’s 1,965 lb and 3,000 lb.
1,985 lb dry and 3,500 lb GVWR, against this model’s 1,965 lb and 3,000 lb.

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.
