I know a few fellow RVers who use cruise-control all the time. I can easily better the MPG by keeping it off. Especially in hilly terrain. I normally pull at 62 to 65 MPH, but will let the rig have its head and run up to 70 MPH (or a little more) going downhill at the bottom when facing an uphill grade. I only apply enough pedal at the start of the grade to produce 62 MPH at the top of the next hill. Obviously, sometimes I get it right and sometimes not. If I have to slow down for traffic, then the plan is shattered :-) My CTD makes max torque at 1600 RPM, but seems to love 2000/2200 RPM. It will maintain 65 MPH on any grade I have been on with it so far, but doing so could burn more fuel unnecessarily. The running start on the downhill works for me.
