At a Perry rally, we drove a Monaco Sig back to back with a CC Affinity, on the same road.
We had heard a lot about IFS, so were really interested in how it compared to the Sig (we then had (and still have) a Dynasty so we were already familiar with the monaco ride).
We drove the sig first, then the CC. At the end of the CC ride, I told the salesman "I don't want to hurt your feelings, but I really don't see any difference in the rides, other than the monaco has better lateral stability." He seemed shocked, but that was our honest assessment.
I mentioned this to a Lazy Days rep. He asked me what kind of road it was. I told him pretty smooth, pretty ordinary, no harsh bumps or expansion crackes, etc. He replied, "that's why the ride seemed the same - on a rough road is where you'll be more likely to notice the difference."
That said, when we got our 02 Dynasty, it road like a truck - a rough truck. We focused on getting it to ride better rather than trading it. We changed the front tires to Goodyear G670rv, added "equal" balancer, weighed the axels and adjusted tire pressure, and finally changed the 4 front shocks to the new Koni FSD. I'll now put its ride up against anything short of a Prevost or Newell.
Ask yourself how much time you'll be driving vs sitting. Ask yourself if the ride is more important than floorplans, ambiance, general personal satisfaction with one over the other, etc.
Then get what YOU like. If either CC or Monaco were substantially superior to the other, one would not be in business. Whether a Cadilac or Lincoln, a lot is just personal preference.
