Those with factory rubber mat.

Ok I know some of you must still have the factory rubber floormat or whatever it's made out of.

So my question is how to you keep moisture out? I've had 3 trucks with them, and all they do is sweat and get water/condensation under them. I'm worried this will rot my floor out. It's been there since 84 I guess, and they are still perfect, but I'm afraid with water there they might start rusting.

On our old 86 k10 I undercoated the floors with duplicolor spray on undercoating. That seemed to work well, as far as stopping it from rusting but it still had water under the rubber.

I ask because I want to put in carpet, but not sure if I want to leave the rubber in and carpet over it, or just remove it and put in carpet.

Only thing I do know is I want to keep the floors in great shape like they are now, and have carpet.

Now it's not a leak from rain, nor a heater core, because it had water under it when it was sitting outside, in the dry and under the carport sometimes, but was warm during the day cooler at night, and without having the truck running. Like I could wipe it out and it be back later. I never did that but I figure it would have.

So any ideas? You guys just leave em alone? Leave it in and carpet over? remove it and then put in carpet? or another option like sound deadening or insulation?
