Pulling a jayco Pinnacle from Los Angeles to Butte Mt

Should take approx 16 driving hours depending on traffic and weather etc. You'll actually only average around 50-52 mph for the 1100 mile distance driven because you'll have to stop for fuel, eating, toilet breaks. stop lights, stop signs, lower speed zones, etc. The faster you drive, the more fuel you will use meaning more frequent re-fueling and higher cost for the trip. It's all about the RV's frontal wind/air resistance which increases drastically as your speed increases over about 50 mph. 68 mph wind resistance is nearing 3 times what it is at 48 mph and that takes additional energy to push the wind. The rolling resistance remains the same regardless of speed driven.

according to MapQuest, you have 17 hours of actual driving time to cover the 1100 miles. For us, this would be 4 days of driving, and we run 62 MPH, which averages out to about 50 MPH.
