Should I have my Citroen Picasso's timing belt changed before a 2000-mile journey?

My 2003 Citroen Picasso 1997cc with a mileage of 84,000 has just had a tow bar fitted, and will be travelling with a caravan on a 2000-mile round trip. Would this require me to renew the timing belt or would it be ok to leave until 100,000 miles?
Definitely have it changed - its tensioner, its smaller pulleys and, if the water pump is driven by the belt, that too. Change the coolant at the same time.
