What’s the difference between rally and leggera 260 motorhome models

The Dometic Rally Air Pro is the superior model to the Leggera as the tube structure goes towards the motorhome rather than across the width of the awning, this gives you more internal space and the Rally overall has more features. The Leggera on the other hand would be lighter weight and pack down to a smaller size. Both are great awnings but it depends on what your preference is
