im also looking for a new van, but needs a payload of around 1.2
Regarding issues, its not very helpful to look on the internet. For every person who types on a forum about a gearbox problem there are a thousand people who have no problems and dont post that on the internet. The renault trafic is a very very popular van so the fact theres a large number of complaints doesnt really tell you very much. Best off just ringing a few garages and getting their advice i think. Personally ive settled on either a trafic, vivaro or transit
