Mk4 1.8tdci Mondeo 5 or 6 speed?

[mk2_fiesta]

I'm in the market for a MK4 Mondeo for a family workhorse vehicle. We'll be buying a small 4 berth caravan in the next 12 months too, so ill be towing with it too. 

My question is, will I see a different between the 5 speed and 6 speed gearboxes on the 1.8tdci (125ps)? My main driving will be on b and a roads day to day. Occasional journeys onto motorways, eventually with the caravan.
