Questions & Answers

    Hi guys, I'm not sure whether to buy the 2 rib or the 3 rib jack. My drawbar is approx 400mm to top of it and jockey wheel mount centre of rib around 330mm. It looks like the 2 rib will do, but how many extensions can you add, just 1 or 2? If your parked on a sloping site you may need a bit longer to level. Will it also be ok with a block of wood under it if required?

    Hello, Thank you for your enquiry. Based on the measurements you are in a position where you can go with either unit as the 3 Rib is able to be mounted the same height as the 2 Rib with the 3 Rib just giving extra height above the drawbar allowing more travel. The 2 Rib is also going to work and an extra extension. If you would like to discuss further, please contact our Showroom Team on 07 5443 1036.  Kind regards, Suncoast Caravan Service
