Don't overfill: you don't appear to realise that unless the airfield has a 'Public Use' licence, you must get permission to land there. OK some airfields grant this on the RTF, but many don't, it's up to the aerodrome authority.
Many airfields have an 'Ordinary' licence which requires PPR and gives their local planning authority the power to impose the condition that the aerodrome authority must know in advance who is going to use the aerodrome.
