Coleman Pioneer 95 top goes up fine but slowly rides down

I trust my lift sytem so little, I cut 1x2s, 46" long to fit next to the lift posts. first things that go in after we pop up, one at the back on the door side, one at the front on the other side, and I bungee them to the lift posts, just in case. yours will prolly need to be a different length, Hope this helps! -Dave
