Shop vac it dry as you can, then you could use the big shop fan to dry it out all the way. I changed out all the rubber door insulation, and it made a huge difference. Now I notice the heat & noise from under the rig, and more so that the extra hole was made for the t-case shifter. I was thinking of installing some of that dense insulated stick on sound mat, on the floorboard for road noise, and helping with heat over the trans tunnel (2-3 layers here) & all of the floor space. You have the perfect opportunity to do that right now!
