finding right cruising speed for economical gas mileage
We just purchased a used 2008 Winnebago View with 5400 miles. Does anyone know a good speed to travel at to get the most out of the mileage? It is a V-6 diesel motor.

Around here the minimum speed on interstates is 45 but the limit is 70. Are you saying everybody is happy if you poke along at 50 in a 70? I'm pretty sure they're not.
OP, slower is the answer to a point. You need to be at the engine's peak torque RPM while your transmission is in it's top gear. That should theoretically be your best MPG.
Frankly, I don't care if they're happy or not. There's a passing lane, so they can go around. On a two lane road, I keep up with traffic.
