Does anyone know what the roof weight limit is on the fleetwood saratoga? trying to find it in teh manual and I am just not seeing it.. I saw a mention that 150lbs is the limit when LIFT or lowering the roof.. I have 2 factory crossbars on teh roof and wondering if I would be overloading the roof with 2 kayaks and my air conditioner. one of my kayaks is 38 pounds, the other is about 80 lbs - but id be willing to buy another lightweigt kayak if the 80lber is going to damage anything..
