I receive a publication for the heavy trucking industry's fleet operators and the current issue had an article on 121 ways to save money on fuel. Many were applicable to RV users, some are obvious and...

So true that slowing down is the biggest fuel saver of all. More savings than all the other's mentioned combined!
The rolling resistance for a given vehicle setup is constant whether at 5 MPH or 80 MPH. However, the air/wind resistance multiplies as speed increases. Like about 4 times the air/wind resistance going from say 40 MPH to 80 MPH and it takes a lot more fuel accordingly to overcome that greatly increased resistance while only gaining a mere 40 MPH. Also saves on brake, tire, and engine wear and vastly increases safety when emergency braking and accident avoidance actions are taken. It's WIN WIN WIN!
