We just ended our first year of RVing yesterday. We drove about 8,000 miles and spent around 135 nights on the road. 3 of the trips were about a month long, 2 of those with 3 "destinations" and this last one spending a month in one location.
Here is what we learned about how far to drive each day.
It takes about an hour or so to set up and tear down. If we are on a "transit leg", with an overnight stop, I try to simply set up / tear down by not hooking up to sewer, and next year I will also just use the fresh water tank more in these instances so I don't have to screw around with the fresh water hook up either.
My wife with drive about 1/3 of the time if we are driving more than 4 hours.
We have done 350-400 miles when appropriate to do so, but distance is also related directly to where you are going to be driving.
I do not want to get caught driving in rush hour in a major city, so you may need to leave later in the day, or end earlier at times to work around rush hours,in either case cutting a day short (we have also driven on 250 one day and 100 the next so that we did not hit Atlanta rush hour on the way home for instance).
Any leg under 250-300 miles is going to be easy to manage in a single day in most cases.
A 500 mile leg would be too long for one day, so we figure out the best way to break into 2 days.
A "destination" that is 400 miles, we would try to make in a single day, given due consideration for where we would be driving.
And yes, we have made reservations for all of our "destinations" well ahead of time. We are taking a 3 month trip later this year, and have all our destinations booked already. We have expected transit stops noted, no reservations, so we will just work those out along the road.
