Failing frame on KZ Durango

Wow, that is pretty severe for just a single 55 gallon FW tank, obviously way under-engineered. We have a pair of these tanks (110 gal total) on our TH and we often carry them fully filled since we prefer dry camping and boondocking, even when staying at RV parks with hookups we always carry at least one tank full, I would be livid as well if I saw this too. We don't have an underbelly on our rig making it easy to see all of our tanks, although each tank is supported by a single rail on either side, their is no evidence of the slightest sag when filled to max. Unfortunately, this has occurred more than it should to many members of this forum, seems that some manufacturers put them on just for looks as they are not properly supported for long term use. Hopefully the repair isn't too tasking.
