Managing steep terrain in a RV can be a challenge. The US Interstate system is designed to move large equipment around the country quickly and safely.
The Interstate System is limited to 6% grades with an exception for mountainous areas where the feasibility of that grade is limited. The exception allows for a narrower road and shoulder up to a 7% grade.
A “6% grade” is the slope of the road. Per cent means per one-hundred so 6% grade is 6 per one-hundred. For every 100 units you travel horizontally you increase your altitude by 6 units. Therefore, for every 100 feet travelled, there is a change of 6 feet in altitude.
Our video depicts one of the steepest and longest grades in the eastern US interstate system.

The Dwight D. Eisenhower National System of Interstate and Defense Highways, commonly known as the Interstate Highway System, is a network of controlled-access highways that forms part of the National Highway System in the United States. The system is named for President Dwight D. Eisenhower, who championed its formation. Construction was authorized by the Federal Aid Highway Act of 1956, and the original portion was completed 35 years later, although some urban routes were cancelled and never built. The network has since been extended. In 2016, it had a total length of 48,181 miles (77,540 km). As of 2016, about one-quarter of all vehicle miles driven in the country use the Interstate system. In 2006, the cost of construction was estimated at about $425 billion (equivalent to $499 billion in 2016).
Thank you for joining me on the quest to enjoy a recreational vehicle (RV). Gail, to whom I have been lucky enough to have been married to for over 30 years, travel in a Newmar Canyon Star 3911.
This is a approximately 40' (39' 11") in length. This Class A is designed to be accessible for a person restricted to a wheelchair, which I am.
To answer the obvious question, as the result of an automobile single vehicle, and occupant, accident in 1973 I suffered a spinal injury at T10 resulting in paraplegia.
Over the ensuing years I have Learned to pilot a single engine aircraft, Commercial license and Instrument Rated, snow ski with a monoski, sail competitively and participate in various auto racing venues. I pursued a career in finance working for several international corporations such as Duracell, GE, Textron.
Happy to be retired after 40+ years of work, I am going to fulfill a dream of using a Class A to tour the USA.
Ever since I saw a GMC Motorhome in the early 70s I have wanted to travel in a Class A.
Finally we decided the Newmar 3911.
