Hi
If its in good condition at a reasonable price then it will do the job fine. It will carry 650 litres and your equipment with room left over. Payload of 1000 kgs or 1250kg depending on model (engines heavier on 2.5), 7.5 cm of load area is more than enough. Also being a Citroen, dual passenger seat was standard.
It is more heavy on fuel than the 1.9 you were asking about earlier today, but no heavier to run than a 2.5 l turbo diesel Ford Transit of about the same age. Trouble is with turbo diesels is that if you push them they use diesel. But then what's a few pounds extra a week for diesel if the van is spot on? A newer Hdi will cost a couple of grand more, so a couple of quid extra a week on diesel is nothing.
Again, gearbox condition is very important - make sure there is no grating of gears when going up and down the box. A gearbox repair at the main dealer will cost more than the van's worth for a proper job - exchange gearboxes are also never repaired properly.
