Agree with several posters, I think you need more miles behind the wheel. I started with my current coach 13 years ago not having driven anything larger than a pick up. I didn't feel comfortable until about 5000 miles into the experience. Too many items to watch and new sounds to get used to in addition to the size of the vehicle. Nearly 90,000 miles later I drive as few as 200 miles in a day or 600, depending on my time and where I'm heading. I personally think the DP would be an overall more enjoyable experience, but your current coach might be fine as well as others have suggested.
