While inspecting things on, under and around the Coach, then hitting my head (again)
on one of the corners of the slide I noticed that the corner trim pieces were a bit loose.
Looking closer it was apparent that there was minimal/no caulking along the edges. I'm sure that water intrusion over time in cold weather climates where expansion and/or contraction of water, forming ice, that has gotten in the opening in addition to warm climates where water could enter and facilitate the growth of mold along the bottom edge of the slide could cause some issues. Not to mention, the chance that the end cap could fall off completely after coming loose over time.
I've attached 3 pictures of how I sealed the edges using "painters tape" and standard clear caulking to hopefully eliminate any occurrence. I hadn't thought of using Entegra's factory sealant at the time, it had been identified at the Spartan Class by P.J. although I forgot the product name but, I think any quality caulking available at a big box store would suffice.
