It would be foolish to pull a load like that at 80 MPH up or down a grade.
It has to do with the superior handling of the coach. Factory claimed you can cruise over 90 if you so choose. So that is the design speed. With a 75 mph speed limit 5 over is not unreasonable if the traffic is light enough.
But what does the tire manufacturer say? Most commercial tires and RV are not rated for that speed!
x2 - I was surprised at the speed rating on my 14 Ply Michelin XRV and Continental HDR tires. And yes I had exceeded that rating a time or two.
