No need to wet vac there are drainage holes inside the tub, easy to spot once you lift the carpet just pop the plastic/rubber caps out.This baby is FILTHY inside from playing on dusty dirt roads so, while I'm thinking about it, can you rinse out a wrangler (after removing the carpet of course) and would that require a wet vac to suck it all out afterwards? I figure if I park so it's leaning pretty heavily to the passenger side and a bit down in the front, most of the water would run out the door. Also, will the carpet hold up to being hosed down and then sun-dried?
