My buddy has a 2004 Rockwood. He's spent the last two years fulltiming. From FL, he's been up the East coast into Canada, and out West to Oregon. I was so impressed by how well his rig is holding up, I bought a smaller version (same brand).
You'll find weight saving construction techniques in most RVs. My last one was a 36' Class A. The cabinets were of no better construction. The rig was 6 years old when I sold it. I lived in it for over a year.
Think you'll find with some research, the Forest River Rockwood trailers have a better reputation than most.
