2007 KOMFORT TRAVEL TRAILER Structure Problems

TL*THE CONTACT OWNS A 2007 KOMFORT TRAVEL TRAILER. THE CONTACT STATED THAT THE BACK SLIDER OF THE TRAILER DID NOT SEAL CORRECTLY. HE NOTICED THAT WHEN IT RAINED OR WHEN HE WASHED THE TRAILER, THE INTERIOR WOULD BECOME SOAKED. SOMEONE SHOWED HIM THAT HE COULD SEAL IT WITH BARS, BUT THE CONTACT DID NOT WANT TO DO THAT SINCE HE FIGURED IT WAS A FAILURE WITH THE TRAILER. HE CONSULTED THE MANUFACTURER AND WAS INFORMED THAT HE WOULD RECEIVE A CALLBACK. HE NEVER RECEIVED A CALLBACK. THE DEALER ATTEMPTED TO REPAIR THE FAILURE SIX TIMES, BUT IT STILL PERSISTS. THE MILEAGE WAS NOT APPLICABLE.
