What's wrong?

The Hehr 6400 Series window on 2018-2020 Showhauler Motorhome, Toter Coach, and Garage Coach vehicles includes a vented glass section. That section is bonded into the window assembly with adhesive, so it stays in place while still allowing the window to open for ventilation.

On affected vehicles, stress can break down the adhesive bond that holds the vented portion of the window. Once that bond weakens, the glass is no longer secured the way it was designed to be. The corrected window design increases the bond strength between the glass panes with an adhesive-backed spacer and a different secondary sealant.

Owners can notice the problem during regular maintenance. Look for a visible loss of bonding around the vented glass, including an edge that looks loose, separated, or no longer fully attached to the window assembly.

Who's affected?

Spans Motorhome, Toter Coach, and Garage Coach builds across the 2018, 2019, and 2020 model years, tied to Hehr 6400 Series windows and the surrounding structure.

Year, model, and body type narrow the scope, but the VIN decides. Check your VIN to confirm whether your specific RV is included.

What's the safety risk?

If the window adhesive fails, the vent portion can detach from the vehicle, increasing the risk of a crash or injury. A maintenance inspection can reveal loss of bonding before separation. Drive cautiously and schedule the dealer inspection soon, especially if the window trim or vent area looks loose. Repair is free at any franchised Showhauler dealer.

What should I do?

  1. Check your VIN to confirm your 2018-2020 Showhauler Motorhome, Toter Coach, or Garage Coach is included in this recall.
  2. Contact your nearest franchised Showhauler dealer to schedule the free Hehr window-vent inspection and replacement that fixes the adhesive failure.
  3. Bring the recall notice if Showhauler mailed one. If not, reference recall number 21V540 when you call.
  4. Avoid driving with any loose window vent until the dealer repair is complete.
  5. Call Showhauler customer service at 1-800-524-5210 with repair questions.

What happens at the repair

At the dealer, a Showhauler technician inspects the Hehr 6400 Series windows and replaces the vented window section when the adhesive bond is not secure. The inspection, replacement parts, and labor are free under the recall. Showhauler has a general reimbursement plan on file. If you paid out of pocket for a related window repair before the recall notice, contact Showhauler customer service and ask how to submit documentation for review.
