We've had our Flex about two weeks now, including our regular 100-miles-each-way-on-twistie-roads-to-Knoxville-and-back trip.
Favorably impressed overall.
1) Rides very solidly and handles well, cornering very flat. Very quiet. Bear in mind it replaces a 21 year old Land Cruiser, and our regular ride is a Honda Element 5-speed, so I guess an improvement was to be expected.
2) Lots of power.
3) Flexible transmission. Click it into "M" and it goes into a "Grade Assist" mode that holds gears longer both uphill for easier revving and downhill for more engine braking. That was perfect for the ride up TN 68 which is quite hilly and curvy. Hit a paddle shifter and you go into manual mode. Good if you want more engine braking. Like it.
4) Lots of room - for up to 7 passengers, with easy to fold seats.
5) Lots of amenities - garage remotes, keyless entry, backup camera, power lift gate, split L/R F/R heater/AC, heated seats with adjustable lumbar support - that sort of thing. The saying comes to mind: "As you get older, what were once luxuries become necessities". I can see how the features could grow on you in a hurry.
At first blush, the Ford Sync is amazing for what it can do. On second blush, however, its not user-friendly or intuitive at all. We're pretty much an Apple family, so I guess we have high expectations. Had trouble with the very final step in getting it to navigate to an address - the screen/voice prompt just seems wrong. And I was trying to scan all FM stations, and it only wanted to scan presets. It's cool when it will stream music and podcasts from our respective iPhones via Bluetooth - except when it won't. Same with calls in and out. We're not stupid people, and will figure this out eventually, but the reviews indicating a steep learning curve were correct. And NOT the kind of thing to futzing with while driving.
We had a Tekonsha brake controller installed at a nearby trailer place and the fellow there felt the base Voyager model was just fine and what he uses. So that's what we got. With the harness in place upgrading later should be easy if it turns out to be inadequate.
As an aside, we are presently leaning away from an Airstream, and leaning towards a 21' Camplite, but that deserves its own thread.
And finally, I come from an aviation background where Operating Limitations should really be taken pretty seriously. As such, I will respect the 4,500 lb limit Ford suggests, especially since I'm new at this.
And since I think the other Flex thread got closed due to contentious opinions on this matter, I ask that this not be debated again in this thread, for fear of shutting it down.
Thanks, and more to follow as our adventure unfolds...
