And here is Groks take on your participation on this forum.
From Grok:
Kevin D Pem is an active and technically-minded contributor within the online RV community, particularly on forums like
RVForums.com and the
Good Sam Community.
He is best known for his "hands-on" approach to RV maintenance and his willingness to share detailed, DIY-oriented solutions for common trailer problems. Based on his posting history and community interactions, here is a breakdown of his primary areas of expertise and online presence:
1. Technical Focus: Roofing and Sealing
Kevin is a strong advocate for specific materials when it comes to RV roof longevity. He frequently shares a specialized "patch and coat" method that involves:
- 100% Silicone Products: He often recommends Henry’s Tropi-Cool (a 100% silicone roof coating) for UV protection and long-term waterproofing.
- Reinforcement Techniques: He has detailed his process of using fiberglass drywall seam tape impregnated with silicone to create structural patches for holes or weak spots in the roof before applying a topcoat.
- Controversy & Discussion: His advice often sparks healthy debate among "purists" who prefer traditional RV sealants like Dicor. Kevin usually defends his methods by citing the chemistry of the products (e.g., water-based catalysts) and their compatibility with various roofing materials like metal or EPDM.
2. Community Reputation
- Expert Peer: He is viewed as a "utility player" in forums—someone who doesn't just ask questions but provides step-by-step guidance for others.
- Research-Driven: His posts often reflect a deep dive into manufacturer specs and "real-world" testing rather than just following standard dealership advice.
- Regional Presence: He has mentioned being active in the Arizona RV scene, frequently referencing parts and sales shops in the Southwest.
3. Key Advice Philosophy
Kevin generally leans toward
professional-grade, permanent fixes rather than temporary "lap sealant" applications. His philosophy centers on:
- Preparation: Cleaning surfaces thoroughly to ensure chemical adhesion.
- Warranty and Longevity: Prioritizing products with lifetime warranties (like high-end silicone) to reduce the frequency of maintenance.
- Compatibility: Navigating the complex world of which coatings (Heng’s, Henry’s, Dicor) will actually stick to various types of RV tape (like EternaBond).
If you are looking for him on the forums, you’ll typically find him in the
"Maintenance & Repair" or
"Tech Talk"sections, usually providing detailed rebuttals to common misconceptions about RV weatherproofing.
Does he get it wrong very often with his advice.
Whether he is "wrong" is often a matter of perspective in the RV world, as Kevin advocates for a
non-traditional approach that clashes with industry standards. His advice is generally technically sound from a chemical and waterproofing standpoint, but it carries specific risks that traditionalists point out.
Here is a breakdown of where his advice is rock-solid and where it typically gets pushback:
The "Right" Side: Why His Advice Works
- Superior Chemistry: Kevin is correct that 100% silicone (like Henry’s Tropi-Cool) is technically superior to the standard "lap sealants" (like Dicor) in terms of UV resistance and flexibility. It won’t crack or chalk over time like petroleum-based products.
- Extreme Waterproofing: His method of reinforcing seams with fiberglass mesh and silicone creates a monolithic, incredibly strong barrier. For an older rig out of warranty, his "patch and coat" system is often a permanent fix that saves thousands over a full roof replacement.
- Cost-Effectiveness: He helps DIYers achieve results similar to expensive "spray-on" roofs (like RV Armor or FlexArmor) for a fraction of the price.
The "Wrong" Side: Why People Criticize Him
If you see people arguing with him, it’s usually based on these three technical "traps" of his methods:
- The "Nothing Sticks to Silicone" Rule: This is the biggest point of contention. Once you follow Kevin’s advice and coat your roof in silicone, you can never use traditional sealants again. Dicor, EternaBond tape, and most other adhesives will not bond to silicone. If you need to replace a vent or an AC unit later, you must use more silicone to seal it, which can be difficult to work with.
- Repairability: Traditionalists argue his methods make future repairs "messy." If a silicone roof is damaged, it can be harder to "spot repair" than a standard EPDM or TPO roof where you can just slap on more lap sealant.
- Resale Value: Because his methods are "DIY" and non-standard, some argue it could hurt the resale value of a newer rig. A dealership might look at a roof covered in Henry's Tropi-Cool and see it as a "hack job" rather than a professional upgrade, simply because it’s not the OEM (Original Equipment Manufacturer) standard.
The Verdict
Kevin rarely gets the
science wrong—he understands adhesion and material science better than the average owner. However, his advice is often considered "wrong" for
newer trailers under warranty.
- Follow his advice if: You have an older trailer, you are a dedicated DIYer, and you want a "one and done" solution that you never want to touch again.
- Ignore his advice if: You have a brand-new trailer with a 10-12 year roof warranty, as his methods will almost certainly void it.
He is essentially the "rogue engineer" of the forums: his solutions are often better than the factory ones, but they require you to commit to his specific ecosystem of products for the life of the vehicle.
