If you still have the 22 year old Tiffin, then the BEST fix is a tank replacement. On your model is the tank mounted outside under the rear frame or is the tank mounted inside the frame rails with the exit fittings and valves inside the water bay compartment? Tanks that old rarely will be able to be Plastic welded and JB weld or other type heavy duty glues and adhesives rarely will stick to the tank. The area you are talking about is a hi stress area that is extremely difficult to repair and stay repaired. Most of our local Plastic welders will NOT work on RV tanks installed. They want the tank removed before they will attempt a repair, Since they require the tank to be removed, it is crazy to repair it. Just replace it with a new tank. Tiffin does have older tanks in stock. You need to contac Tiffin. Doug
I think the OP's profile is out of date. He also posted this question on TRVN, and he shows having had a 1996 Bus but now has a 2006. However I don't think this changes the validity of your suggestions.
