Good to know the 80s are working out for ya. I installed a pair of 60s awhile back and like them quite well, but I'll bet the 80s would make the lift essentially effortless. If I had a concern with the 80s it's the additional effort that might be necessary to drop the roof against that higher force, esp. if it's windy out. Please give us an update if you discover other pros or cons as time goes on. Thanks,

Well, I wouldn't say it's effortless, but...... raising the rear of the roof is now, somewhat easier. Raising the front is much better. Lowering the front IS completely effortless. It is a two finger operation. Goes right down gently, easily. Haven't tried it yet in the wind, though. Although, when we had the 60 lbers, we did set up camp on a high ridge in Utah a couple of months ago, with the rear of the camper facing a 30-35 mph wind and after I unlatched the roof and then opened the rear door, the roof blew, up. Surprised me. Gave me the idea....what if, those fantastic fans were more turbine like, could set them to blow "in", shut the door, turn them on, and blow the roof up like a ballon!
BTW, on our roof, is an aluminum luggage rack, yakima track, and solar panel.
