On the way into kendal on one way section there is an old church on the righthand side for parking not much room there but you can drop down to the old Sunday school type building and park there we managed with 7m coach built. Buildings were for sale last year so it may have changed. Apparently you can overnight at the cticket club for £5 so could park there.
Leisure Centre on the A65 (Skipton Road) should be OK. If I wasn't in Scotland enjoying myself you could use my drive. The "carpark past the church" is not far from my house. And there's another one about 200yards further on - Peppercorn - coaches regularly use it.
