The grocery store where I shop has several dried fruit options in bulk. My favorites are dried apricots, figs, dates, and mango slices. All of them help give me my sugar fix along with fiber and nutrients. Most of all it's good for weight control.
This article lists several great dried fruits and their nutritional benefits and discuss which ones to avoid. Some dried fruit is processed with sugar and other flavoring. Try to find ones with no additives. If you can find your favorite dried fruit on sale, it makes the shopping trip even better!
Lastly, travel vegan can be difficult at times. However, if you pack plenty of dried fruit for the trip, it makes life much easier!
