Our '07 has the '06 chassis & engine and is the same size Ventana. Had 20k miles when purchased 6 years ago. Now has 76k. We'd put probably 45-50k miles on with a motorcycle on a lift, but the last 5-6k towing a GMC Acadia. It has been an excellent machine for us. It does have a Banks system on it, which supposedly boosts the horsepower. As mentioned earlier, it climbs mountains slowly at times, (if you lose momentum there isn't much acceleration), but it has been a solid performer.
In April we drove it coast to coast. The last 1400 miles was straight through with one fuel stop being the only time the engine was turned off (towing the Acadia).
It also has motion control valves and Koni shocks. Had it checked out at Henderson's in Grants Pass in 2016. They gave the chassis a good going over. All it needed was to replace the existing Koni's and have it aligned (minor adjustments).
We have model 3330 and if the floor plans works for you, it is a solid coach. Hope you find something that meets your "wow" factor at the desired price.
