Take the carpet out. Take the doors/windows/flap off. Pull floor plugs. Put trash bags over driver seat. Wait for rain. Jeep floor clean. No carpet to hold moisture. <insert smiley face> I've ran without anything on the floor for a couple of years now. In the spring, I take the doors off, rear-side windows off, and rear window out. I put them back on when it gets cold. I don't even cover the seats anymore. It gets wet.......it drys. I can get a downpour the evening before, and have dry seats the next day. I keep saying I'm going to liner it, but what I have keeps working...no rust yet. Just keep the rug out of it and you'll be fine.
