I'm ripping the carpet off mine and putting on MoanstarLiner
. Water and mud comes thru the holes and wet carpet is not a good thing. My a/c hates it and cost me money to treat the system for bad odours and bacteria. If you can't breathe, you can drive either.
Been using Husky molded front and rear on the WJ for a few years. Front left and right not a biggie, they sort of fit. Not 100% but close enuff.
