While it can be done, in general wind power generation are impractical for nomadic use.

Consider this anecdote:

On my small 37-foot monohull I have 400 watts solar and a 400 watt (theoretical) windgen.¹⁾ From my experience in the mid/upper latitudes mostly summer months, I would say my windgen provides about 15 to 20% of my power needs, while the solar does the bulk… I would recommend you add more solar first. Only once you've topped out with that would I suggest a windgen. – Mike OReilley²⁾

Wind generators require

• sustained winds, which are rare where nomads choose to camp
• high mounts, with bases on the ground or mounted to the vehicle
• a way to “dump” load to keep the gen from overspeed damage in high winds
• teardown in very high winds

Generally speaking, windgens with higher max outputs have higher minimum “start-up speeds”, or speeds when the vanes start turning. Vandwellers in normal wind conditions will likely bias toward low start-up speeds, resulting in relatively low max outputs.
