Hi Alan, we have a 2.0HDI Picasso with a tow weight of 1300kg and we have a 4 berth Bailey Ranger 2004 model and it is superb. The MTPLM of the van is 1237kg but we are under that by about 40kg's or so. With a 1.6HDI you could go for a similar van but you will have to make it work up the hills. Just take your time choosing, do you need a 4 or 2 birth, don't go and get a humungus awning, we have a Sunncamp Ultima 390 and a bedroom inner that fits in so we accommodate 6 people very comfortably. Good luck in your choice, keep us informed. Gary
