Why Middle Tennessee Trusts TwinCraft

Your RV or boat is more than an investment — it’s how you spend time with family and make memories. We help protect that.

Done Right, Not Just Done Fast

We fix problems at the source, not just the symptoms. Quality work that lasts so you're not back in the shop next month.

Columbia Shop + Mobile Service

Bring it to our yard or we come to you — marina, campground, or driveway. Plus emergency service when you're stuck.

Standards That Matter

Marine work follows ABYC standards. RV work follows RVIA guidelines. Proper repairs done the way they should be.

Services We Provide

From routine maintenance to complex repairs and upgrades, we handle the work that keeps you enjoying your boat or RV.

Electrical Systems & Power

Electrical problems are among the most common issues we see in both boats and RVs. Factory wiring often uses undersized cables, cheap components, and designs that prioritize cost over reliability. Add years of modifications by previous owners, and you end up with systems that don't work correctly.

We troubleshoot electrical issues systematically, finding root causes rather than just treating symptoms. When upgrades make sense, we design systems properly — correct wire sizing, appropriate fusing, quality components, and clean installations that will last.

Popular electrical services include LiFePO₄ battery conversions, solar panel installation, inverter upgrades, charging system improvements, and complete rewiring for older vessels and RVs.

Leak Detection & Repair

Water damage is the silent killer of RVs and boats. By the time you notice a leak, the damage has often been happening for months. Soft floors, delaminated walls, mold, and rot all start with water getting where it shouldn't be.

We take a methodical approach to leak detection. Water travels, so where you see damage isn't always where water is entering. We find the actual source, repair it properly, and address any damage that's already occurred.

Common leak points include roof seams, windows, doors, slide-outs, through-hulls, hatches, and deck hardware. We also handle the structural repairs when water damage has already taken hold.

Seasonal Maintenance

Proper winterization protects your investment during cold months. Frozen water in plumbing, engines, and generators causes expensive damage that's entirely preventable. Spring commissioning ensures everything is ready for the season ahead.

Our seasonal maintenance goes beyond the basics. We inspect systems, check for developing problems, and catch issues while they're still minor. Regular maintenance prevents the emergency calls and extends the life of your equipment.

Fiberglass & Structural Repair

Fiberglass repair requires attention to detail and the right materials. Whether it's cosmetic gelcoat damage, structural cracks, or water-damaged core material, we do the job correctly so it lasts.

We handle everything from minor gelcoat scratches to major structural repairs. Proper fiberglass work isn't about quick fixes — it's about restoring structural integrity and appearance the right way.
