HiLo left in up position.
When it is left up for prolonged periods of time, it leaves all the cables and pulleys under stress. If you do leave it up for more than a couple of days, or even a week, you might do as I have done. Raise the top, measure the space between the frame and the underside of the top where the rubber pads are located, (four locations) then buy a two by four at Lowes, cut four boards to these 1/4" longer than your measurements, and label their locations. When you raise the top the next time, go just slightly above the normal stop position and place the boards in their perspective location. As the top settles to its normal raised height, the two by fours will take the strain off the pulleys and cables.
If there is any danger of high winds while you are away from camper, I wouldn't suggest leaving the top up. Hope this helps.
