I have a Voltage 3950 and I've noticed a soft spot on the rood. It's about even with the back end of the living room slide. There appears to be a 5" long slice in the rubber roof in the middle of the soft spot. I looked at it before and thought only the white part of the roof was cut but because of the soft sport and a 3" circle showing some water damage on the inside, I guess it's through to the wood. I must have hit a branch or more likely a branch fell on the rig.
Anyway, I'm wondering if I need to cut the rubber roof to remove the soft plywood OR if it's OK to glue a 2'x2' 1/4" piece of plywood over the soft spot then seal it with white stuff. A 2' square should be enough to straddle two roof ribs.
