Looking at a 2001 Triple E Signature diesel pusher. Never owned a diesel coach before, only gas units. At 24 years old, what are the critical inspection points I should focus on? Should I be concerned about the age, or is Triple E known for quality construction that holds up over time?
Triple E built quality coaches in Canada. At 24 years old, focus on this specific units condition rather than brand reputation. Critical inspection points: water damage, engine hours, service history, roof seals. Get professional NRVIA inspection before buying.
The 2001 Triple E Signature diesel pusher is generally a solid, well-built RV, but at 23+ years old, you'll need to budget for significant maintenance and potential component replacements. Triple E was known for quality construction and attention to detail, but being a 2001 model means you're looking at aging systems across the board - engine, transmission, electrical, plumbing, and slideouts. Expect to invest $3,000-8,000 in the first year for deferred maintenance items like cooling system overhauls, brake work, tire replacement, and slideout servicing. The good news is parts are still available and these coaches have a strong owner community for support.
The main concerns with a 2001 Triple E Signature stem from age-related deterioration rather than inherent design flaws. The Caterpillar engine (commonly 3126B, but verify specific engine model) is bulletproof but the cooling system components - radiator, water pump, and hoses - typically need attention around this age. The Allison transmission is reliable but requires fluid and filter changes every 12,000 miles (severe service) that many owners neglect.
Electrical issues are common due to corroded connections, especially in the battery compartment and slideout motors. The original Intellitec power management systems can develop glitches, and 12V house batteries from 2001 are long overdue for replacement. Slideout seals and mechanisms often need rebuilding after 20+ years, with typical costs of $500-1,500 per slideout depending on complexity.
Structural concerns include roof membrane replacement (if not already done), window seals, and potential delamination around baggage doors. The original Dometic appliances may need repair or replacement, particularly the refrigerator cooling unit and air conditioning compressors.
Get a comprehensive pre-purchase inspection from an RV technician familiar with diesel pushers, budget $300-500 for this. Focus on engine compression test, transmission service history, cooling system pressure test, and generator load testing. Check all slideouts for smooth operation and water intrusion signs. Inspect the roof thoroughly for soft spots and membrane condition.
Research the specific floorplan and year for known issues on Triple E owner forums and RV.net. Verify maintenance records, especially engine/transmission services, roof work, and any major component replacements. Budget realistically - plan for $5,000-10,000 in first-year maintenance beyond the purchase price.
Understand that diesel pusher maintenance is more expensive than gas motorhomes but offers better driving experience and longevity. Parts like air bags, leveling jacks, and diesel engine components cost significantly more than gas coach equivalents. However, the Caterpillar engine should easily go 300,000+ miles with proper maintenance.
Start with immediate safety items: brakes, tires, and steering components. Budget $2,000-4,000 for six new tires if they're original or over 6-7 years old (check manufacturer specifications) regardless of tread depth. Have the brake system inspected and expect to replace pads, rotors, and potentially calipers on a 23-year-old coach.
Address cooling system next - flush and pressure test, replace thermostat, water pump if leaking, and inspect radiator core. This typically runs $800-1,500 but prevents catastrophic engine damage. Change engine oil, fuel filters (primary and secondary - depressurize fuel system before filter changes (follow manufacturer's depressurization procedure - diesel fuel under pressure can cause injury)), air filter, and transmission fluid with filter - about $400-600 total.
Service slideouts by lubricating mechanisms, adjusting travel limits, and inspecting seals. Replace slideout seals showing cracking or shrinkage ($200-400 per slideout for seals, $500-1,500 for mechanism rebuilds). Test and service generator - change oil, air filter, fuel filter, and spark plugs for gas units or check glow plug operation for diesel units.
Update electrical systems by cleaning battery connections, testing charging systems, and replacing house batteries if over their expected life (flooded lead-acid: 3-5 years, AGM: 4-7 years). LED conversion saves power and reduces heat generation. Consider upgrading to lithium batteries and modern inverter/charger systems for improved boondocking capability.
Engine and transmission work should be handled by qualified diesel technicians familiar with Caterpillar 3126B engines and Allison transmissions. Cooling system repairs, brake work, and suspension components require specialized tools and knowledge. Expect $120-150/hour labor rates at diesel shops.
Slideout mechanism rebuilds require specific expertise and tools - don't attempt these yourself unless you're very mechanically inclined. Electrical troubleshooting for complex systems like Intellitec power management often requires professional diagnosis with proper test equipment.
Consider joining Triple E owner groups and the FMCA (Family Motor Coach Association) for technical support and recommended service locations. Many owners travel to specific shops known for quality Triple E service, such as Monaco/Holiday Rambler service centers that still support these coaches.
