Another coach, Class A, that is known for their safety cage construction, is Rexhall. We toured the factory and they showed us a 40' DP with two large (T-Rex) slides. (Bill Rex is the REX in Rexhall
!) The owners had to dodge a deer in New Mexico, and went off the road and crashed into a tree at a pretty high speed. Both walked away, shaken, and minor injuries. The RV was flat bedded back to Lancaster, CA to the Rexhall factory. The gent giving the tour told us that they had hooked power back up to the coach, and tried to open the two large super T-Rex slides - they came in/out with no problems. When you saw the front end damage, and yet the couple survived, and the frame and construction was so well built that the slides still worked - well, it was a 1000 words...
Agree in Class C that Lazy Days and Born Free would be on the short list. Though I consider Born Free to be closer to a Super B then a Class C - but that's how I look at them
If you drop years, the Wanderlodge and Blue Birds are like tanks... Stories of these rolling over, being righted, and then driving off...
Best to you,
