In my case, I'd wait until I reached 10% or less. Reason? My new truck came with free oil changes for quite a while. The catch is, the % needs to be 10% or less. But, if you are paying for the oil change yourself, and it's not part of your "sales" package, then yes ... go ahead and change it. It won't hurt a single thing.
If you do have the service plan with oil changes, then plan on getting the oil changed while you are on the road. I've done this a few times in the last 30 years of camping when my vehicle was approaching or past due on an oil change.
