RE: Help - Water in the hole!
I didn't weigh my board before the water got in and after it got out, although it felt quite light after the van treatment. My dark coloured van on a 90 degree day sure heats up like an oven. When I first opened the door I could see the drops coming out of the vent and hear a bubbling sound. And a good sized puddle on the rubber mat under the board. Perhaps a combination of both methods is best. (upside down first to drain the bulk of the water, and then right side up for the last bit)
