01 What Winnebago publishes for the M-Series
Winnebago Industries, Inc. lists 3 M-Series travel trailers in its 2025 M-Series brochure. Winnebago prints a dry weight for every one profiled here, and each has a page of its own. It prints a GVWR for every one too. Winnebago prints no cargo carrying capacity for any M-Series floorplan, and this site does not compute one. (How the data is verified.)

Read from Winnebago’s 2025 M-Series brochure, 6 Nov 2026. “Not published” means the maker prints no figure; nothing is filled from another model, year or dealer.
03 Reading Winnebago’s figures
A maker’s published weight is for a base trailer; options and dealer-installed equipment add weight to any particular unit. The federal weight label inside the trailer carries its own unloaded weight, cargo carrying capacity and GVWR (49 CFR 567 and 571.120): read it on the unit itself before any towing decision.
05 Recalls
No campaign in either of our passes over NHTSA’s recall record names this line. That is not the same as a clean record — a line can be recalled under a parent name, and prose matching is imperfect. Treat it as no result found, not as no recalls.
Coverage is not complete: this list is a starting point, not a clearance (how it is built), so check a specific VIN at NHTSA before you buy and again before you tow.
No campaign is filed under the Winnebago M-Series name. Winnebago’s older IF and WF Series motor homes are a different product.
06 Owner-reported problems
A sweep of NHTSA’s complete complaint file — every safety-defect complaint NHTSA has received since 1 January 1995, matched on NHTSA’s own model field under every name this site publishes for the line — found no complaint naming this line. Treat that as no report found, not as a clean record: owners file under whatever name they were sold, and a newer or lower-volume line simply has fewer owners to file.
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.
