There are usually two, three or four 1/16" steel straps about 2.5" wide that are attached to the frame runners under the tank. These straps are all that hold the tanks in position. There is "sometimes" (depending on the type of "polar pack") some insulation under these straps and then the coroplast is installed.
The tanks are made of a flexible plastic that holds its shape, but with the added weight of water, will bulge on the sides and droop on the bottom. If the tank is not leaking and the straps are secure, it's probably OK. I'd start a list of "things for the dealer", put it on the list and the next time you take it in for warranty work, have the dealer check it out to be sure.
