01 What makes it unique
Aliner lists the 2026 Evolution 15 at 2,400 lb dry, a GVWR of 3,500 lb and a tongue weight of 200 lb. Aliner prints no cargo carrying capacity for it, so none is given here; the federal label inside the trailer carries one.
It is 18' long and 69" high folded for travel. Aliner prints its tanks as 35 gal fresh.
Among the 13 models Aliner lists for 2026 with a published dry weight, it is number 11 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 15 differs from the other twelve Aliner floorplans. Most distinctive first. How these ranks are worked out.
- Tongue weight as a share of dry weight, 8.3%: second-smallest of thirteen, between the Amp (7.7%) and the Classic Twin Bed (8.8%).
- Dry weight, 2,400 lb: shared with the Evolution 15 Twin Bed; of thirteen, ten lighter and one heavier, nearest the LG (2,390 lb) and the Amp (2,600 lb).
- Fresh tank, 35 gal: largest of eleven, level with the Amp, Evolution 15 Twin Bed and LG; next are the Classic Rear Sofa/Mattress, Classic Twin Bed and five others (11 gal).
- GVWR, 3,500 lb: highest of thirteen, level with the Amp, Evolution 15 Twin Bed and two others; next are the Classic Rear Sofa/Mattress, Classic Twin Bed and six others (3,000 lb).
- Length, 18 ft: longest of thirteen, level with the Amp, Evolution 15 Twin Bed and two others; next are the Classic Rear Sofa/Mattress, Classic Twin Bed and four others (15 ft).
- Interior height, 8 ft 3 in: tallest of thirteen, level with the Amp, Evolution 15 Twin Bed and two others; next are the Classic Rear Sofa/Mattress, Classic Twin Bed and four others (8 ft 1 in).
- Tongue weight, 200 lb: shared with the Amp; of thirteen, seven lighter and four heavier, nearest the LXE (180 lb) and the Evolution 12 (210 lb).
Next to the LG, the nearest lighter floorplan by dry weight, the 15 is 10 lb heavier by dry weight and has a tongue weight 40 lb lighter; the two publish the same GVWR, length, interior height and fresh tank.
Next to the Evolution 15 Twin Bed, the floorplan with the same dry weight, the 15 has a tongue weight 40 lb lighter; the two publish the same dry weight, GVWR, length, interior height and 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 (3,500 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).

04 Notes on this floorplan
What Aliner does not publish for the Evolution 15
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
2,390 lb dry and 3,500 lb GVWR, against this model’s 2,400 lb and 3,500 lb.
