Help with water puddling on camper cover

The CalMark cover for my Lance 1055 accumulates puddles when it rains and the standing water eventually degrades the cover material. The puddles tend to form between high points on the roof, like the A/C unit, the storage racks, even the above bed hatch and the refrigerator vent. I have a new cover and am trying to make it puddle-proof, so far unsuccessfully. I've tried placing inflatable balls, approximately 12" diameter, under the cover to make a constant slope to the edge, and putting balls on the high points to force a constant downward slope but neither of these ideas has worked.

Have any of you had this problem? And if so do you have any remedies you're willing to share? My last cover lasted 8 years but it would have lasted even longer were it not for the material degrading where the puddles form.

Thanks for any help.
