It is very easy to take the top off. Roll down the rear window and remove about 14 or so bolts, maybe more around the interior edge and along the cab roof line and whatever trim accessories that might be under the bolts, then pick up the cap using two people, one on each side like a coffin. There are two pins, one on each side used as locating pins to align the top upon re-installation. Depending on the number of years, it may be "stuck on" the side rails and what I did was to get inside and push up with my back against the top and push up to break the seal.
I loved driving with the back off and if it rains, drive faster on the highway and even the rear seat passengers will not get very wet. Otherwise carry a tarp around for those parking moments in bad weather. Think like a biker in this regard.
