Habitation Servicing but not as we know it

I moved last year from a "conventional" Coachbuilt Motorhome to a Panel Van Conversion. My new Van has a compressor fridge and diesel heating and thus gas is only used for cooking (grill and hob). Looking at the National Caravan Council Habitation Service Checklist about 50% of the service operations are irrelevant. Furthermore constructional simplicity and integrity mean that about 90% of service operations which are essentially checking and inspecting roles could be carried out safely and confidently on a DIY basis. Does the Club or other members have any advice to offer or experience of trying to obtain a customized HAB Service more relevant to my needs.
