which dual cab

Found this site a week ago and have been sitting up late nights trying to absorb the drift and the more I read the more concerned I get about a few little things. Now I dont want to start another war but just want some (objective??) straight info. The lady and I have got to the stage of wanting to caravan and trying to sort out what sort of van ... at this stage likely poptop around 16ft. Now I have looked around at what to use for a tow vehicle and decided that it would be a dual cab diesel. looked at the hilux,navara,rodeo and triton. Then it got down to the navara,hilux and rodeo and then because a lot of years ago we had a good run with nissans (not 4wd) we decided that we would probably buy a new Navara with the zd30 motor. I thought I could put that on the back-burner and concentrate on what the caravan was going to be. THEN I find this site and start reading all nissan problems which to me seem absolutely incredible - gearboxes, oil problems , turbos failing, clutches wearing out way too early,motors exploding,things breaking etc etc etc. I mean to buy something that a) I intend to keep for a few years and b) should give me a good run without major dramas and major expense. Hey I know its not a perfect world (more than ever now) but these vehicles represent many hard earned smackerooz and in 2004 I figured Nissan and co would have things pretty well sorted. So now I'm not so sure anymore and will have to review choices and try and find out a bit more 'truth' (doncha love this net ). I think I will still give the triton a miss but what about the rodeo - its really an isuzu isnt it? What do you all think about this and how they rate overall and as tow vehicles for vans around 15 or 16 feet. Think I want diesel not petrol. Is there something else I'm missing?
