Hi, i am proposing to fit an electrically operated cooling / heating fan to my Truckman canopy on a17 plate Barbarian as i have 2 large dogs and would like to be able to keep them cool/warm as the case may be whilst travelling. I would like to have it fitted on to the forward glass panel as opposed to the roof and to be operated via a dashboard switch, any suggestions or advice would be very much appreciated ( professionally supplied and fitted would be preferred as i would'nt trust my d i y skills ) . Thanks
