Well, is not that I am competing in a race. Was pretty much a shakedown trip and see what is capable. Yes MPGs drops like a rock. 70 MPH got me around 10 MPGs and 65 got me about 13 MPGs. My biggest fear was about instability at a safe cruising. At least I know the limitations and 65 MPH seems to be a good speed to chug along. That I could bumped to 85 MPH, sure, why not but I see no reason to be near that. One neat thing is if you get back on a semi trailer and is doing a speed that you are comfy with. The draft will give you at about 4 more MPGs and I was not at its rear bumper; I was a decent distance from it. Another thing, when passing a rig, experienced very minimal sway, if so, it was controllable on a predictable manner. Seems the Reese DWH is doing its job really well.
