Coming alone now. by the window if its not damp i would just sand it down and use car filler to make it look better and then paint the hole window frame .and paint the cupboard doors as well a nice cream or very light gray make it look more modern .i wouldn't vanish them .you should get most bits from the caravan breakers have you checked the gas to the hob yet . And you need a upside-down pineapple sticker in the window as well 😉
