Without doubt this is one of the best businesses I have dealt with. I have had the need to consult them on three different occasions and I might add because of my own neglect, and they have either honoured warranty 5 years later or replaced parts I have lost with no questions asked. On top of this the OzGlide is just so much ahead of the competition. My van, contents and car ride so smoothly and it should be standard fitment on all larger caravans. Not cheap but Quality should not be about the price and this is one product I am happy to open the wallet for. Thanks again OzGlide for your impeccable aftersales service.
