we have a 2004 fiat ducato swift kon tiki and on a recent trip away (march - april) on starting out we experienced some clutch slip. This carried on till we got to dover (we live in somerset), with some periods of clutch slip, however from the next day on for the remaining 3 weeks no matter how hard we tried to make the clutch slip IT DID NOT. Ther last trip made in the motorhome was Xmas to france and small amoiunt of clutch slip within first 24 hours of use. No usage in between trips. My question is has anybody else experienced this is it common when vehicles are not used? for long periods of time. The milage is only 28,000 miles. any comments gratefully received.
