Go for a discovery 4 ... with the air suspension option. One of our riding group has one, easily fits three bikes with front wheels off on an internal rack with the seats up, or as many as you need on the towbar mount. His wife drives it without complaint and it seats seven if required.
Pretty bombproof inside, and talk about off road ability !
Will keep up with my XF over most drives, and far more practical, milage low to mid 30's overall (around 5 less than mine).
Having said that my Thule's will easily hold three bikes, and the boot is just enormous. What is annoying is taking the rack on and off (mainly due to wind noise, MPG is negligible). Have recently put a pulley system in the garage (intended for kayaks) basically loosen off racks feet, hook four bungee cords and pull it up to rafters and tie it off.
I tend to shy away from estates due to the lack of security for work equipment but do like the Subaru allroaders (prob be my next looker).
Spent several years in NZ and Aus in a variety of utes, from Ford Couriers to Hi-lux and more recently a Maloo (which was simply insane) While the Maloo was fun to drive the rest were very "agricultural" and while a couple had seating for four, anyone put in the back hated you after half an hour. Shotgun was hard fought for around our way!
Think "family friendly truck" is a bit of a misnomer personally.
