2027 Grand Design Imagine AIM20BHA

Grand Design publishes an unloaded vehicle weight (UVW) of 4,538 lb and a GVWR of 6,395 lb for the 2027 Imagine AIM 20BHA, with a hitch weight of 468 lb. It does not publish a cargo carrying capacity on the floorplan page, so none is shown here, and none is worked out by subtracting one published figure from the other. The trailer’s own federal weight label, inside the door, carries its cargo capacity as built.

It is 23' 10" long, 10' 5" high and 8' wide, with 37 gal fresh, 45 gal grey and 37 gal black tanks as Grand Design lists them. Fresh water weighs about 8.3 lb per US gallon, so a full fresh tank adds roughly 307 lb before anything else is loaded.

Among the 6 Imagine AIM floorplans profiled from Grand Design’s 2027 pages, it is number 4 of 6 by unloaded weight, in a range from 3,547 lb to 5,361 lb. Every figure in that comparison comes from the same Grand Design page type for the same model year.

Every number on this page was read on 19 Oct 2026 from Grand Design’s own floorplan page for the Imagine AIM 20BHA, whose structured data names the model year 2027.

How the 20BHA differs from the other five Imagine AIM floorplans. Most distinctive first. Each rank counts only the siblings that publish that field, and a figure most of them share is left out.

• Tongue weight as a share of dry weight, 10.3%: smallest of six; next is the 21MBA (10.4%).
• Length, 23 ft 10 in: second-longest of six, between the 19MLA (22 ft) and the 21MBA (24 ft 11 in).
• Dry weight, 4,538 lb: third-heaviest of six, between the 19MLA (4,361 lb) and the 17MKA (4,945 lb).
• Tongue weight, 468 lb: third-lightest of six, between the 16MLA (432 lb) and the 19MLA (478 lb).
• Sleeping capacity, 5: largest of six, level with the 21MBA; next are the 15RBA and 16MLA (3).
• Exterior height, 10 ft 5 in: shared with the 19MLA; of six, two lower and two taller, nearest the 15RBA and 16MLA (10 ft 2 in) and the 17MKA and 21MBA (10 ft 10 in).

Next to the 19MLA, the nearest lighter floorplan by dry weight, the 20BHA is 177 lb heavier by dry weight, has a tongue weight 10 lb lighter, is 1 ft 10 in longer and sleeps three more; the two publish the same GVWR, exterior height, fresh tank, grey tank and black tank.

Next to the 17MKA, the nearest heavier floorplan by dry weight, the 20BHA is 407 lb lighter by dry weight, has a tongue weight 57 lb lighter, is 2 ft 2 in longer, stands 5 in lower and sleeps three more; the two publish the same GVWR, fresh tank, grey tank and black tank.

Grand Design lists 6 Imagine AIM floorplans for 2027. 6 without an existing page here are profiled from Grand Design’s own floorplan pages, from 3,547 lb to 5,361 lb unloaded; the others link to their existing pages. Grand Design publishes UVW, GVWR and hitch weight for these trailers, and no cargo carrying capacity.

Closest sibling: the Imagine AIM 21MBA, nearest on the published figures. It differs on 3 of the 8 fields both publish (this plan first): length 23 ft 10 in vs 24 ft 11 in; dry weight 4,538 lb vs 5,361 lb; hitch weight 468 lb vs 560 lb. They match on sleeps, GVWR, fresh tank, grey tank and black tank.

Either side of it by GVWR: Imagine AIM 19MLA matches it at 6,395 lb GVWR; Imagine AIM 21MBA matches it at 6,395 lb GVWR.
