I must admit, I’m a little mystified by this whole discussion. After 35 years of RVing, we had to sell our 3100 due to age/health issues. This was after first owning a 2900 (no longer made). The 2900 had wandering steering, a hot doghouse, and was kind of noisy. But then, after all, it was a truck. The 3100 was a vast improvement. It drove great, much quieter, no floor heat problem, and for us, a perfect floor plan. We weren’t too concerned with minor issues while driving as that was generally a small part of our time in the PC. And for us, the speakers was not an issue as we rarely used them – using driving time for sightseeing, planning, talking, contemplation, and being thankful that we had this lifestyle. Frankly, we didn’t spend money on trying to fix things that only involved driving and didn’t affect our camping experience. Just my humble observations.
