I think the answer depends, in part, on what you like to do. If you like sight-seeing, where you drive to a point of interest, see it, and hop back into your vehicle, you will want to move often.
If, on the other hand, you like to hike or bike, you may want to spend more time in one area, do the hikes or the rides, and then move on. That second model is what we do -- the trailer is our basecamp, and we take the truck each day to a different trailhead.
With this setup, we can access trails within a 45 minute drive of the trailer, in all directions. That's a lot of terrain! (Stuff that is an hour away is not convenient -- we'd spend two hours a day in just "commuting" to the trailhead.)
The advantage of a "basecamp trailer" is that you don't have to pack up all your stuff every day. You leave it in place for several days before moving to a new area.
