01 What makes it unique
Aliner lists the 2026 Evolution LG at 2,390 lb dry, a GVWR of 3,500 lb and a tongue weight of 240 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 10 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 LG differs from the other twelve Aliner floorplans. Most distinctive first. How these ranks are worked out.
- Dry weight, 2,390 lb: fourth-heaviest of thirteen, between the Expedition Rear Sofa/Mattress (1,985 lb) and the 15 and Evolution 15 Twin Bed (2,400 lb).
- Tongue weight, 240 lb: heaviest of thirteen, level with the Evolution 15 Twin Bed and Expedition Rear Sofa/Mattress; next is the Evolution 12 (210 lb).
- Fresh tank, 35 gal: largest of eleven, level with the 15, Amp and Evolution 15 Twin Bed; 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 15, Amp 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 15, Amp 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 15, Amp and two others; next are the Classic Rear Sofa/Mattress, Classic Twin Bed and four others (8 ft 1 in).
- Tongue weight as a share of dry weight, 10%: shared with the Evolution 15 Twin Bed; of thirteen, seven smaller and four larger, nearest the Ranger 12 (9.9%) and the Evolution 12 (10.7%).
Next to the Expedition Rear Sofa/Mattress, the nearest lighter floorplan by dry weight, the LG is 405 lb heavier by dry weight and has a fresh tank 24 gal larger; the two publish the same GVWR, tongue weight, length and interior height.
Next to the 15, the nearest heavier floorplan by dry weight, the LG is 10 lb lighter by dry weight and has a tongue weight 40 lb heavier; the two publish the same 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 LG
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
1,985 lb dry and 3,500 lb GVWR, against this model’s 2,390 lb and 3,500 lb.
2,400 lb dry and 3,500 lb GVWR, against this model’s 2,390 lb and 3,500 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.
