Sorry to hear about your slide awning damage. Our same year 377RLBH toppers got damaged by a ferocious hail storm in Llano TX, last Apr 12. And 2 mos prior, we (DW and I) removed all four slide toppers to have them double-restitched after five years fulltiming. They are same as yours, Carefree of CO and all the stitching had decayed to the point of the seam letting go on the 13’ kitchen slide. As the remove/reinstall repair took almost a week, I decided not to keep all the roller springs locked at a tighter tension for days as each roller had 48” of fabric wound. So I and the DW loosened all the rollers 10 turns(it was arbitrary-and I only felt a small difference in lesser torque still at that point) before I locked it down for several more days until the fabric was repaired. I’m guessing if the roller is about 3” dia, x 3.14 pi = 9.4” circumference, or about 5 turns to wind 48” around them. So, obviously I let out 5 more turns too many. Then two months later, the hailstorm struck with 1.75” hail and made Swiss cheese out of the kitchen and dinette toppers. Amazingly, the master and bunk house slide toppers were spared.
So again, the DW and I removed the old toppers and put on two new Sun Pro 18oz ultra 10 year replacement fabric($359) and are very satisfied with their quality. They are glued with no seams to disintegrate. I’m sorry I couldn’t tell you how many turns to zero tension, but can only guess you should have at least 10-15 turns in front of the 5 to wind the 48” fabric for 20 max total. But do a dry practice tension wind first and always have an extra set of hands and extra screws (3/16” dia I think) when unwinding and rewinding the roller. If you can’t find out from the mfgr, climb a ladder on another rig similar topper to get a feel of the tension and 9.5” of fabric or so per turn to get near even tension for varying width slides. Good luck. Let us know how many roller turns it needed before installing the fabric.
