Hi BeeeBeee
I have my car converted 2 and half years ago and had the valve saver system put in to which I have made 2 trips one to Benidorm and one to Italy and never had a problem as long as you get it serviced every year you won’t have a problem at all as I have done a lot of miles and the trip to Benidorm I was towing a caravan if you look at my pics you can see it and it’s cheaper than just petrol hope this helps you
