Thank you so much Lock ‘n’ Level for the superb service I have received after I had an issue with my unit. Repaired and returned through UPS in time or our next jaunt. This has to be the most convenient and easy way of levelling a caravan EVER! I just wouldn’t want to be without my blow up friend!! (Didn’t think I would ever use that sentence! ) Thank you L ‘n’ L – you have made levelling my caravan a breeze!!!
