Alternative to an Airstream's quality and beautiful windows?

Again not to bash Airstream. They are works of art, and I might buy another despite previous issues. Ours was a 2004. Be very careful of units used or stored near the Ocean. They have corrosion and easily observed upon inspection. Secondly, clear coat peeling from the aluminum exterior. When it starts it keeps growing and looks horrible. Not sure if it has been corrected, some are in a very expensive process of stripping it and polishing the unit.
