The safari/bikini top and tonnau cover are my year around setup. My full soft top has only been back on during tropical storms with a few days of heavy rain.
Safari will keep YOU basically dry unless its windy and raining blowing sideways in on you. Parked in the weather with upper doors on seats usually do stay dry. Upper doors off and the safari top keep a set of 55 gallon cheap seat covers in your rig is a good idea.
*** Water will pool in the safari top, remember to push it off after a rain otherwise when you turn it runs right down your seatbelt or just splashes down onto the seats.
Check out the spider web shade. It is attached differently and can stay on under your full top as another option if you are just dropping the full top and not removing it.
