We just picked up our Solera 24R on 2/28 and drove from Des Moines to San Diego. Love the look of frameless windows. They seem adequate for ventilation especially with the fantastic fans going. Only had one incidence. While staying overnight in Santa Rosa, NM, we were hit with some strong 50 mph gusts that rocked the Solera even with the stabilizers down. Next day about a half an hour into the drive there was a loud noise and the rush of air. The left rear emergency exit window had left the vehicle. Both red locking tabs were up. Was it the wind from the previous night or were the tabs never secured in the first place? Don't know. However, from now on checking those locking tabs are on my pre-flight checklist.
