My 2013 Autotrail Apache 700 (Fiat Ducato 130) is due it's third year service in April (10200 miles). Habitation service booked with Teesside Caravans for £140. Tried North East Trucks for the engine service and quoted £400 for what they call a "short service" oil fuel filters etc. anyone up here have any recommendations or advice? Greatly appreciated.
