I'll travel for a year and needs a good backpack with wheels. I'm thinking of 55L or 65L. I a problem in the back so I need something with wheels. I would prefer one without a pack a day.

Reading your question I think we need something different, not a backpack with wheels, not the baggage that is 55L or larger. Unless you expect to be able to carry your luggage for an hour or more, do not bother to buy a backpack with wheels. The larger the package, the less likely you'll use in backpack mode. For a large, I think a suitcase with wheels is much better than that can be converted. And The other point is the size. If you go to a place and stay there you may be able to travel with 55L or 65L. However, if you travel from one place to another, you will not want much. To travel around, most people take what they use in a week and do laundry when it's dirty. When you get tired of wearing the same clothes over and over again, to buy something new and throw some more out. You can pack clothes for a week in a "rolling if cabin '. If I were you I would buy one of those cheapish and use. If you find you want more clothes or need more space for souvenirs or whatever, you can buy a larger box and leave the old behind. Buy clothing which may cost more, but you'll save a fortune in storage tanks need not, and you will be happy while traveling, how to really move around. I'm down to size backpack to travel for weeks in Europe and now there is no need to store my luggage to go to town. But any type of luggage you decide buy, go to a store where you have several different test and compare different types and find the one that is best suited for your body and your limitations. Having a back problem may also restrict the ways in which they can bend and pull.
