Winterizing Woes: Keeping My Sierra 3800RK Leak-Free ๐Ÿ’ง



 It’s Wednesday, February 26, 2025, and I’m bundled up, thinking about a winterizing win with my 2024 Forest River Sierra 3800RK that saved my bacon—and my budget ๐Ÿ’ฐ. Last November, I noticed a drip in the rear kitchen of my fifth wheel ๐ŸŒง️—a slow leak near the skylight above that fancy island counter ๐Ÿฝ️. With 42 feet of luxury to protect, I wasn’t about to let water ruin my hardwood floors or that plush master bedroom ๐Ÿ›️. Time to play handyman!


I grabbed a ladder, a $10 tube of Dicor self-leveling lap sealant from Camping World, and climbed up in the chill ❄️. The Sierra’s roof is a beast—EPDM rubber, tough but needy—so I scrubbed the skylight seam with rubbing alcohol ๐Ÿงผ, then squeezed that gooey sealant like frosting a cake ๐ŸŽ‚. It oozed into every crack, hardening overnight. Next day? No drip! I didn’t stop there—checked the slide-outs (all four of ‘em! ๐Ÿšช) and resealed a corner where wind had pried at the caulk. Inside, I ran the furnace ๐Ÿ”ฅ to dry any damp spots, sipping cocoa ๐Ÿซ on the sofa while the Sierra hummed back to life.


That rig’s a dream—big pantry, washer-dryer prep—but leaks don’t care about luxury. Today’s a perfect day to eyeball your 3800RK’s seams before spring rains hit ๐ŸŒฆ️. What’s your winterizing win? Drop it below—I’m taking notes! ⬇️


Happy trails! ๐Ÿš✨
