Keystone service campaign 25-474
Keystone filed this with NHTSA as a service campaign dated Nov 6, 2025, received Nov 5, 2025, about the unknown or other — 3 documents under this number. It names 4 model years (2026). A service campaign is not a safety recall — there is no NHTSA campaign number and no federal requirement — but it is usually work the manufacturer pays for on the vehicles it names; the dealer checks the VIN against the manufacturer’s list.
What the bulletin says
Source: NHTSA's summary of the manufacturer's communicationIt has been determined that certain models with underslung axles may have insufficient clearance between the axle beam and the holding tank located above the axle. The lack of clearance may cause damage to the holding tank.

The summary is NHTSA’s abstract of the document, as filed under 49 CFR 579.5; the full text comes from the manufacturer or a dealer. One communication is usually filed as several documents — the bulletin, a dealer notice, an owner letter — and the number on any of them finds this page. Quote it at a service desk; it is what the dealer’s system is keyed on.
Model years it names

None of these model years has a page on this site (it covers EPA-certified cars, trucks and SUVs from 2016), so the bulletin is listed here on its own.
Common questions
Source: NHTSA, 49 CFR 579.5Is Keystone 25-474 a recall?
No. A service campaign is a manufacturer communication filed with NHTSA under 49 CFR 579.5; a safety recall carries an NHTSA campaign number (two digits, a letter, six digits) and a federal duty to repair for free. Check the vehicle’s recalls by VIN at nhtsa.gov/recalls.
Is the 25-474 repair free?
A service campaign is usually paid by the manufacturer on the vehicles it names, within the terms and time limit the document sets; the dealer checks the VIN against the manufacturer’s list.
Which vehicles does 25-474 cover?
The manufacturer filed it against 4 model years: 2026 Keystone Aspen Trail, 2026 Keystone Colorado, 2026 Keystone FUN Time, 2026 Keystone Zinger. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
