We have a 1999 Jayco Designer 5th wheel. Kitchen holding tank has cracked and I have had it repaired 2 times and it is leaking again. I have ordered a new tank from Jayco to replace old one. I want to know if anyone has had a similar problem (and what caused the problem)and if you have a recommendation for a different type of holding tank and best way to install. I have a 1999 Ford F250 diesel.
