For my two penny worth, don't consider a 4x4. you get reduced fuel consumption all yr round for wanting to tow 10 days out of 365. WE have an MPV (VW Sharan) although there is lots of choice. Much more flexible in terms of use and solo MPG in mid 40's - its a diesel. 7 seats great for family trips, and with all seats out, load space is terrific.
Just watch your kerbweight, but a Sharan is heavier than a Freelander, and Touran is too. I have an Elddis Odyssey and towing stability is superb.
