Airstream is my dream brand for me.
Specifically, the 34 ft triple axle beauty!! Adding a slide out model would just be the bees knees for me.
Anyway, thats my wish list.
Okay, okay, since you asked... what makes them awesome?
How about towing safety?
They are low to the ground
this gives them a low center of gravity
They are generally balanced very well and are generally not prone to sway
they handle exceptionally well and track behind a vehicle great.
They don't have a lot of storage... they have less headroom. Not perfect, unique, and they have staying power.
Thanks!
