Have just purchased my first motorhome, a hymer 544k, first registered in Jan 02 with 23,300 miles. Dont know the first thing about cam belts, but have read a few posts where it seems to be the main topic of conversation! Would you think the cam belt should be replaced on my motorhome, or will there be a few more years/miles before it is necessary? Anything else I should be thinking of changing/checking on a vehicle of this age? Thanks in advance for any helpful info!
