The vinyl flooring issues are mainly due to the way our trailers are built. The full width of sheet vinyl is attached at the perimeter before the inside fixtures and any partition walls are installed. When the partitions and cabinets are installed, this shrinks the amount of area to often a few feet so that when cold weather comes, the vinyl sheet that is between these small spaces can't withstand the contraction and they split.
I did mine with 8mm laminate plank, probably the cheapest Lumber Liquidators sells. Even though it has an attached back, I installed a rubber subfloor underlayment. I've had it in the trailer for two winters in MN and no problems to date.
