I have no dog in this fight. Presently, we own a Forest River camper. I only signed up here to ask questions about a new Altitude toy hauler.
We bought a Heartland Cyclone 370C in 2011. Had it two years and the day we sold it was absolutely awesome. Not only was it terrible but dealing with Heartland was an absolute nightmare. The first month we owned it, the brakes failed. Heartland said it was not their problem and I needed to deal with Dexter axle! Heartland got the $60,000 the month before but then they wanted nothing to do with us. From there, it continued on. My dealer was very helpful but even they grew quite frustrated with Heartland.
As you said, they are great to deal with before the sale. AJ and the others are very kind at that point. But in my experience after the sale, I'll sleep on the ground in a tent before I buy another Heartland camper.
