I do agree, after what I went through on my slide, I will never own another slide camper without a topper.
100% agree here. I don't want to speak for John, but what he discovered was that water runs down the exterior side of the slide out, and via surface tension runs under the slide bottom before dripping off. This allows water to wick in and rot the floor. John discovered and repaired this, and I followed his tutorial when repairing my rotten slide floor as the damage had been caused by the same situation.
The fix was to install a drip edge on the bottom of the slideout sides so that water dripped straight off without following under the bottom, so it has no chance of wicking in.
The slide topper awning is wider than the actual slide, only by a few inches, so that water drips directly off the awning and not down the side of the slide.
This may or may not have been your particular issue, so your fix may not be the same, but if the floor rotted once it will rot again unless you find the root cause. If not, sell it now while it's newly fixed!
