Not having a factory installed filter is my choice to be honest. I simply use one of the in line filters that hooks up to the water hose feeding the RV. They can be picked up at Walmart, Home Depot, Lowes, or any hardware store not to mention Amazon.com.
Adding a filter is kind of a piece of mind item. When we go out we usually stick to bottled water for drinking and use the RV park water for dishes, showers and such.
An inline filter will cost anywhere from $14 to $20 if you choose to go this route.
And Oh Yea, Congratulations on your new Wildcat. The more time you spend in it, the more you will be impressed.
