When I went to Alaska I averaged 8.5 mpg on the highway driving at 55-62 mph. In Alaska I averaged 8.3 mpg because the roads were dirt could only travel at 40-45 mph which means I was in 3 rd gear most of the time. Weight plays a role also. I was heavily loaded on that trip always traveled with full tank of water and a lot of stuff. Ave for most trips was 8.7 mpg.
I've noticed that my average MPG is better in town than at any highway speed, unless there is a tail wind. Even though that means not being in high gear. Otherwise, on the highway, the slower the better. Just my observations.

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.

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.
