This Service Advisory requires a Pre-Authorization & Photograph
Note – Check serial number on Key Express to verify the campaign is open. Some vehicles were repaired before they left Keystone.
When performing warranty or recall service, please make certain that appropriate Personal Protective Equipment (PPE) is used.
The remedy is to inspect the clear polycarbonate skylight on the new Alpha Flex Roof system. Inspect the clear skylight for cracks and replace if cracks are found. See Figure 1 as an example. A clear picture is required for authorization and the claim.
Please Note: The affected units have a new roof system that is different than what you may be accustomed to seeing. The membrane looks very similar to the old membrane and the only way you may be able to tell them apart is the sealants. The new self-leveling sealant is more like a rubber consistency and is more resilient to the elements. Alphathane 5121 self-leveling is the only type of self-leveling sealant that can be used on the Alpha Flex roofing system.
Step 1
Locate the trailer on a level, flat, hard surface. Chock the wheels.
Step 2
Locate the skylight on the exterior roof and inspect for cracks. If the skylight is cracked, take clear pictures for the authorization showing the defect. If no cracks are present, proceed to warranty reimbursement below and submit a claim for inspection. If the skylight is cracked, proceed to Step 3.
Step 3
If the skylight is cracked, remove the skylight using normal industry standards and replace with the new skylight (KRV # 237000) using butyl tape (KRV # 100292) under the skylight as a primary seal and Alphathane (KRV # 639155) as a self-leveling secondary seal, then proceed to warranty reimbursement.
