Clean those chassis drains early and often

I was a bad boy. I went to the gas station where I spend about $60 on gas a week and used their vacuum ($2) and sucked up all the water. If its sunny tomorrow, I'll leave it with the top down in the sun.

They seem to take ages to dry out properly due to the plastic base layer in the carpet. Mine felt slightly damp after weeks out of the rain!
Some folk recommend taking the seats out and drying the carpet indoors so when i took mine out, as a precaution, I made a plastic membrane for the electronics unit, This was vented at the top for air/heat circulation. just in case!

I've not had this problem in the Box yet (hope not to!), but I had a Camry as a DD at one point. Occasionally I'd have one of those summer days when I'd drive to work in sunny weather and I'd leave the windows open an inch or two, only to be surprised mid-afternoon by a sudden torrential, drenching, cats-and-dogs kind of downpour.

Once home, I'd mop up what I could---towels, and I've also got a Shop Vac. Following that, I used to set up a box fan (on High) in the open door of the car, sometimes changing its orientation after a couple of hours to hit spots that were still damp. If it's nice out, I'd leave the car in the sun in the driveway while I did the fan thing, otherwise in the garage. Obviously, open all the doors---consistent airflow over a few hours and things were dry as a bone.
