Is the RVR an Outlander in the US?
We have a Mitsubishi Outlander and a Chrysler Town and Country. We've also had smaller sedans...
The Chrysler T & C is our favorite to drive to FL.
The Mitsubishi Outlander is our 2nd favorite. (T & C's third row make it easier for someone to get horizontal to nap, and for a parent to sit and supervise some of the crafts the kids do in the second row. Otherwise it would be a tie).
All sedans we've ever had are in third place.
Both the T & C and Outlander, despite being higher or heavier than the sedans, perform so well on the highway (gas mileage), that whatever extra savings we'd get from taking a more economical vehicle isn't worth losing the comfort of those first two vehicles.
YMMV.
