How fast do you drive your Class A?

I'm curious what others have found to be the magic point between rig capability, speed, and fuel efficiency. I'm not talking about when you are sauntering along just enjoying the scenery, but rather when you just want to Get There. My last class A was an underpowered DP that could barely get up to 65 on the interstate. I haven't pushed my current (gas) rig because I haven't had all the mechanical issues fixed, but it did 65 on the state highway and didn't seem to be straining. Haven't had it long enough to see what the mileage is like.

If you feel like sharing how you selected your preferred cruising speed, that would be great too.

So the rig in your sig is "vintage" so I'll share how I like to drive my '84 Allegro.

It will do 75-80 MPH if/when I want it to. The 454 is about red-lined with the 3-speed trans, but in a life-or-death situation I've done it. That kind of speed is not comfortable or sustainable.

Mine feels best at around 60 MPH...maybe 65. As I approach 70 MPH I can feel it. Gets a little sketchy.

Fuel economy is best at 55-60 MPH. But, again, I don't have overdrive. 55 MPH feels dangerously slow on a 65 MPH highway.
