How to sequence points for GPS collection?

I have a large number of points representing assets that I need to field verify. Their unique IDs reflect when they were created, which is not a good indicator of how close they are to each other. Using ArcGIS 10.3, how can I sequence these points in a logical order for exporting to a shapefile that will be transferred and updated on a Trimble GeoXH unit?

I do not have a geometric network in place, and haven't had any success using the "Find Route" tool, probably because the points aren't addresses on a street.

My thinking is some kind of model that calculates the closest point from a defined starting point (Near tool), writes an n+1 integer to a sequence field, then iterates to select that next closest point and repeat the process.

I have very limited coding experience and am hoping there is an easy tool or small set of tools to use instead of having to code a large, complex model.
