Replacement Flooring Options

We had the misfortune of experiencing severe shrinkage of the vinyl flooring in our TT upon return to our home base in Northern IL in late Jan '14 due to illness and passing of a parent. We went from AZ temps to several consecutive days of sub zero temps here in Rockford, IL. Just the other day I discovered a 12" long split in the vinyl flooring from a floor register to a dinette base cabinet. So we are also seeking advice and input as to the most practical replacement flooring for our TT which will be exposed to extreme temp variations as long as we are based in Northern IL. I have a son who works in in the flooring department of Home Depot and he encouraged me to avoid most every vinyl product other than possibly 12" self stick tiles due to their simple replacement should future expansion and contraction present further problems. A hardboard laminated flooring was also suggested as long as adequate edge space was allowed for expansion and covered by a base shoe of some type. Any other solutions out there that others have found to be successful in remedying this contraction condition?
