Real Owner Reviews: Freightliner vs Spartan
Freightliner Owner Feedback (2024–2026)
“2026 Tiffin Phaeton on PowerGlide XC – 8,000 miles already. The Freightliner handles like a dream on highways, and the new 5-year warranty gives total peace of mind. Towed our boat up the California coast effortlessly.” –@RVAdventurer45 (iRV2)
“2025 Newmar Dutch Star – value is unbeatable, but added SumoSprings for tighter corners. Service at any Freightliner spot is quick and cheap.” – Good Sam Forum
Spartan Owner Feedback (2024–2026)
“2026 Entegra Cornerstone K3 – IFS transforms mountain drives. No sway in gusts, and the Aebi Schmidt merger means even better parts supply now. $10K upcharge? Totally justified.” –@EliteRVer (iRV2)
“2025 Newmar New Aire K2 – smoothest ride ever, V-Ride eats up potholes. Custom build fits our 44-footer perfectly, but rural service requires planning.” – RV.net
“Love the torque on the X15, but drove 180 miles for a tag axle alignment post-merger—improving, though.” – Tiffin owner, 2026
