Thanks guys, this is helpful stuff.
I'd be probably leaning more towards the D22 (as much as I'd like the D40 by the sounds of it).
Whats the fuel economy like with them (both 3l and 2.5)?
I actually have 4 kids (all under 8), though they only come in my car on occasions, and usually not all at once. So leg room wouldn't matter so much.
We have a 2010 D22 2.5L diesel purchased new.
Leg room is the issue when they get older. I can sit in the back but it is a bit tricky getting in and out. Okay if the person in front is short legged.
Context; this is our first 4x4. Before that we drove Mazda vans. a 1600, then 2000, so the 2500 is a powerful enough for us. There was also the petrol to diesel engine change experience(no real engine breaking).
Which reminds me that the 4x4 mode requires manual hub locking, if that is an issue. I just lock them in when I think I might need 4x4. the manual says to do if occasionally anyway. IMO, the advantage of manual locking is that on places like boat ramps, you can select 4x4 low mode and operate 2WD to get the pulling power.
If you are a rev head, you might not like the lower power until the RPMs hit 1,750 when the turbo kicks in. Once i knew that little fact, I understoof WTf was going on.
If the kids need special seats, then you'll need the mounting/attachment points put in.
Firstly, if you are above average height and solidly built, make sure you sit in the D22 with the door shut and check that you can close the door and don't trap your leg and can do the require stuff. My little Bro thought he would be okay for a joint trip away, but short of a 3/4 amputation, no way was he going to fit.
Fuel economy, say 11l/100Km around town to 15l/100Km lead footing up the highway towing a 1.6T Camper trailer. Those are real calculated figures from a running economy sheet.
If you like love toys, then forget it. The vehicle is also a PITA when you try to run GPS, hand held radio, mobile phone recharger and other shit as there is only the passenger floor to put it.
OTOH, it is a relative simple vehicle that has 2" higher clearance than the D40, so you can crawl under it okay with out turning your head sideways.
I don't know about the D40. but the tub on the D22 will not take a "standard" pallet if that matters. also missing the tie down rails that the D40 has.
We had two reasons for buying the Nav. SWMBO said the seats were the most comfortable and the pile of information and assistance available on this forum.
