Ok, got an update, Frenchie got back to me and you are correct in looking for an external rack. He wrote "The rear mounts on the frame and the front to the windshield hinge. This will work with the hard or soft top. The hard top is not strong enough to carry any weight."
I can give you some guidelines to look for, manufacturer recommendation is a moving target, they are improving their designs all the time. Years ago when I looked into expedition racks the weights were staggering averaging something like 150 pounds. Ended up going with a thin walled large diameter tubing for the exoskeleton and alloy load bars to hold the tent. It was strong enough that it didn't deflect much at freeway speeds, maybe 1/64 of an inch. The alloy crossbars worked well, if I remember right we only used two as the strength was in the rack. Weight was something like 65 pounds. Chris at Landrunner went into production with a similar system, here is his link - http://www.landrunner.com/workshop.html
You will need to click on the "Camper Top" button to see the rack - the old Maggiolina looks a little dated, alway like this one as it had a space on top to strap crap that you didn't want in the truck. Just remember to delete the basket as it adds weight that you don't need, the tent is your basket.
