How fast do you drive your rig?

63 mph when roads are clear, 55 if windy or even slower in rain and wind

+1 62-63 mph seems to be the sweet spot

I'll go 65 at the most pulling our 5th wheel but it's smooth with no sway. If I had a class A diesel pusher, I can't say I wouldn't go 70 ish. I know how my truck is maintained though.

I as just driving on I495 North on Mass and I was passed by a Monaco Monarch doing around 80 MPH. It was swaying from side to side as if there was a wind issue but there was no wind. Also he was towing a trailer and that was swaying quite a bit. I see DPs doing 80 quite often but never see gassers like this one doing it. The man was making tracks for sure.

When I drive my rig I tend to do so between 55 and 65. That is my comfort range with my 37' gasser. What is yours?

Depending on what year Monaco Monarch it was, it could have had the GM 8.1L engine and Allison transmission, which like my Monaco, will do 80MPH, and then some. ECM fuel shut off is at 5000 rpms. 65 MPH cruise is about 2200 rpm's.
I wouldn't recommend going 80 MPH since he was probably exceeding the speed rating of his tires, but the drivetrain would certainly allow it.
Me, I drive as fast as I feel comfortable with that day, depending on road conditions, weather, traffic, etc. It has served me well for about 300,000 miles in various Class A coaches. If I worried about fuel mileage, I would not have an RV.

Like Rwake, we cruise on the interstates about 63 mph. Off interstates, I just make it a point to never go over the speed limits.

55-60, it's rare if I go above 60. On the Interstate, I stay in the right lane as much as possible. If I'm on a two lane highway, I'm constantly watching behind me & pulling over for others to pass wherever possible.

I don't think I would want to do 80 in a gasser. Fuel economy would suck and it would be a white knuckle experience.

60 MPH towing or not.

I always stuck to the posted Truck speed limits. Our 32' Class A was too thirsty at speeds over 60.
