Bought this Burstner 748 without the sink infill. Have been quoted, nearly £100.00 for a replacement!!! Motorhomers can you help get a cheaper one?. Now I know you jokers are just itching to reply with a witty retort, but I have heard most of the cracks, regarding,Choppers etc,so please keep it serious. Which is on reflection, an invitation for all the old jokes to come flooding in!!
