My late husband loved liquid and used the Helios system at home and on the road. We had Apria for O2. If we arranged ahead of time with them, they would have the large liquid unit waiting for him at the hotel we were staying at and , if we stayed long enough to need it, would refill it(this assumes you are staying in one place). They also had a smaller resevoir that you could use in the car (had to arrange for this ahead of time).
I must admit that I thought compressed (with lots of tanks) seemed easier. With a national supplier like Apria you can arrange for filled tanks wherever you are.
Again, read your way through the portable oxygen site. There are pros and cons to everything.
If you need it 24/7 on your trip, does that mean that you are using it 24/7 now? If so, what are you using now? If you are using 24/7 anywhere you should have a good portable arrangement of some sort and not just a concentrator.
