I have just purchased a new Bailey Ranger GT60 520/4, as this is my first caravan I am slowly finding my away around the caravan. I would like to ensure if I have a puncture I can safely lift the caravan with an appropriate jack I would like to fit a Kojack Caravan Jack & Levelling Aid, is this suitable with this caravan and are there the correct securing holes within the chassis. I thank you in anticipation for your help in this matter.
