For safety, a ladder that extends above the roof is better. It gives you the opportunity to grab hold of the ladder before you step onto it.
Handy hint, you also want the base of the ladder far enough away from the Airstream for stability, and a longer ladder makes that easier. OSHA and CoE say one foot out for every four feet up, but there's an easy way to tell without measuring. When you're setting up the ladder, put your feet right between the ladder's feet. Then reach straight forward. The ladder should be at an angle that lets you grip the ladder side rails with your arms almost
fully extended. If you have to lean forward to grip the ladder, the angle is too shallow. If you can lean backwards while holding the ladder so you'd fall back if you let go, the angle is too steep.
