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.

Welcome to the forum. Slower is usually more economical.
In our Class A gas Southwind I usually travel about 58-62 mph. That gives me the best mileage and isn't unreasonably slow.
I don't know about a diesel but, I would think the same is true.
Mine is a gasser, but I have found this to be accurate. Faster uses more fuel. As a matter of fact, 16% faster (72mph) gives 25% reduction in mileage (8mpg down to 6mpg). Slower (55mph) causes it to downshift more often on small grades, causing it to use more fuel. I usually set it on 62.
