All depends on what you value your time at.
Here is an example of 5,000 miles at an assumed 3.899 per gallon across the trip, at a hypothetical 75@10 and 65@12 (mph@mpg). That is a 10.25 hour difference in raw drive time which equates to about $32/hr cost by going faster.
If you limit your drive time per day, that 10 hours is 2-4 extra days of travel based on a lot of people's limits. If you then convert those extra days to campground costs (unless you HH/BW/boondock/moochdock) that is $40-200 eating into the fuel savings, plus additional meals, laundry, etc.
