I am looking at buying a u1300l from tuxford. They have about 15 which all have low kms but high hours?? Which seems wierd as they don't have a pto I can see.
They are all looking tired with some showing cab rot. With them being 366t does that mean they all have fast axles??.
I am thinking at least 2k to get it serviced changing fluids and belts, filters, repair cab there is an air leak on the one I looked at and some dash parts missing.
What sort of money should I be looking at??
