Which Pump for Tyres and Floe

Sorry i know this question has been asked many times but I'm still frustrated. The tyres on my caravan require 65psi and i wish to find a suitable pump to achieve this they are currently about 55psi. I've studied the forums and the one that seemed most popular was the Ring RAC600. Now i do have which seems the exact same pump but does not have any label. This reached about 60 psi then failed making a strange noise. Now i really don't know which one to buy and would appreciate any recommendations. I also have a Floe drainage kit which needs 15psi so i would need it to be pretty accurate. I would particularly like users experience with the RAC600 as although looking exactly the same mine maybe just a badly made copy !
