D-1's EZLift or something like it. Why? It is simple. No hydraulics or anything complicated. Sometimes simple is better and when it comes to cover lifters, I think its true. Store here has been open 8 years. We have sold 5 different lifters. Beachcomber's Lift'n'store (an EZLift knock-off) was the most reliable. The EZLift is constructed better than the Lift'n'Store, the bars are thicker.
