I have a 2019 Coleman Lite 2425RB TT. I have two cracks in my fresh water tank. Specs say it is a 60 gallon tank. I had the tank drain open this winter but it got down to 12 degrees (almost unheard of in south Louisiana). It caught me off guard. There must have been a small amount of water in the corners or low spot below drain level. I tried a handy man repair with JB Weld and Eternbond tape in the two 3 inch cracks but it did not hold. I'll have to replace the tank.
My question is: With the corrugated fiber board needing to be removed and then getting the tank out being beyond my expertise and ability, do I go back to a dealer, shade tree repair guy, or what other option might I consider?

This^^^.
I have replaced two myself. It's not terribly hard/complicated but you need to be able to get on the ground and crawl , slide shimmy on the ground to get the job done.
I see it as an easy job for a young man. A miserable job for an old man...LOL

Since the cracks sound accessible, it might work trying to plastic weld it. First drill small holes at the ends of the current cracks to stop their propagation. Plastic welders can be had from harbor freight and other places.

Original poster :
Since both cracks are accessible I'm up to trying again to do a repair. Since JB Weld covered with Eterna bond tape didn't work could anyone give me any suggestion as to what other material I might try.
Has anyone ever use the "as seen on TV" Flex Seal or Flex Tape on an RV tank?
I also saw a video using the heat head and plastic rods melting the plastic in a crack. I'm working under the RV on the bottom of the tank. Would I be able to use that melting method if I'm working upside down? I'm almost 70 years old and I can crawl under to work on the project but I'm really not up to removing the tank.
