    Stainless steel or Poly tank in a tanker? Thoughts?

    Poly. Lifetime warranties available, and lighter in weight.

    Just my thoughts.

    After years with steel tanks, poly for sure. Unfortunately, the true best tanks, made by Custom Fiberglass, aren't available any more.

    UPF Poly without a doubt. Lifetime warrantee for as long as you own the truck.

    Stainless is good but can get brittle over time.
    If you go elliptical go Poly and you can put a shiny wrap on it, as long as you have probies to keep it polished.

    Depends on what the trucks going to be used for. We have poly's on our engines and tankers, our tanker normally stay on the road. Our neighbors have a "tactical tanker" - and when he went through a ditch - not sure if the tank moved or the frame flxed - busted the poly tank in half. Sure it's guaranteed - but the trucks out of service until they can get another tank installed.

    I think the problem with poly tanks is that they "float" and are not (at least from what I have seen) bolted down where a stainless steel or fiberglass tank would be bolted down.

    A poly tank should be mounted securely to a rigid subframe that is attached with spring loaded mountings to allow the chassis to flex without affecting the tank. I've seen the same thing happen with a stainless milk tanker that was moved onto a new chassis and not given any flex capability.

    Default Depends on usage

    In our neck of the woods we are sometimes called upon to supply "potable" water. I've been told you must have a SS tank for this (not positive though). We have a 3000 poly and a 2000 SS. Some pretty rough roads, no issues with either.
