01 What Keystone publishes for the Fuzion
Keystone lists 6 Fuzion toy-hauler fifth wheels for 2027. 5 have a complete Keystone figure set and a page of their own here; the others are listed below with the reason against each. Across those 5, Keystone’s shipping weight runs from 15,890 to 17,540 lb, its carrying capacity from 3,460 to 3,960 lb and its hitch figure from 3,745 to 4,060 lb, on lengths of 39′ 6″ to 46′ 8″. Keystone publishes a shipping weight, a carrying capacity and a hitch figure for each, and no GVWR; those are Keystone’s terms and are kept, so this site does not call them dry weight, cargo capacity or a loaded rating (how the data is verified).

Read from Keystone’s Fuzion roster (keystonerv.com, read 5 Nov 2026), which lists these floorplans under the heading “2027 Floorplans”.
03 What Keystone does not publish
No GVWR, no unloaded (dry) weight under that name, no cargo carrying capacity under that name and no exterior width appear on Keystone’s Fuzion floorplan pages, so each spec page reads “Not published by Keystone” for them and none is worked out from the three figures Keystone does print. The federal weight label inside the trailer’s entry door carries its unloaded weight, cargo carrying capacity and GVWR (49 CFR 567 and 571.120): read it on the unit itself before any towing decision. Keystone notes that its website reflects the most recent production run and that features and specifications change during the year.

How this count is drawn. A report is counted here only when NHTSA’s own model field names this line. What the owner typed in the description is never used to attribute a report: our line names are ordinary English words, and an owner writing “imagine my surprise when the axle went” or naming the state of Montana is not reporting a Grand Design Imagine or a Keystone Montana.
Read these as reports, not as findings. Complaints are submitted by owners and NHTSA does not verify them; no complaint here has been confirmed as a defect, and none of them is a recall. The sample is also self-selected — only owners motivated to file appear in it — so a high count tracks how many units a line sold at least as much as how well it was built. Use the pattern, not the total: a component that keeps recurring is worth inspecting on any used unit. File or search complaints at NHTSA.
