2027 Grand Design Imagine3100RD

Grand Design publishes an unloaded vehicle weight (UVW) of 8,076 lb and a GVWR of 10,195 lb for the 2027 Imagine 3100RD, with a hitch weight of 879 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 35' 11" long, 11' 3" high and 8' wide, with 45 gal fresh, 90 gal grey and 45 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 374 lb before anything else is loaded.

Among the 7 Imagine floorplans profiled from Grand Design’s 2027 pages, it is number 7 of 7 by unloaded weight, in a range from 6,218 lb to 8,076 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 3100RD, whose structured data names the model year 2027. Grand Design marks this floorplan as dealer stock.

How the 3100RD differs from the other fourteen Imagine floorplans. Most distinctive first. Each rank counts only the siblings that publish that field, and a figure most of them share is left out. Not every one of these pages covers the same model years as this one (2027); each figure is the one its own page prints, so a rank compares pages, not one model year.
