I bet it is even better than 10% I went from a 25' Airstream and gas pickup to 24' class C. The overall weight is very similar between the rigs. The truck/Airstream got about 20 percent better fuel economy overall under most highway driving conditions. Its not quite fair because the C is taller and more frontal area.
