Ok, i just got caught in some pretty bad weather tonight down at Beaudesert. The Mt Lindsay Hwy is a 100klm zone but i did about 20klm in 1st gear because the rain/hail/golf balls were so bad. FIRST FRIGGIN GEAR and i still couldn't see shiat. It's the worst i've been in for quite a while. Now my jeep has an inch of water in there mostly on the floor behind the front seats and i had to pull the plugs, remove the roof to let it air and lift the carpets up a bit. Hopefully it will dry out tonight
So, yes in very heavy rain you will get drenched if not moving very fast. However, everything under the tonneau is dry as it could ever be. That tonneau's sealing ability is amazing!!! It's just the friggin bikini sides that suck!
The biggest issue is the water pooling on the bikini and the tonneau and when you turn a corner or whatever it just pours in the sides. My jeep was parked outside all night with the combo on in the heavy rain and i only really got water into it when i took off
There is more heavy rain forecast for the next few days so i might resort to putting the full top on tomorrow if it keeps up.
