Hello Randjg1 -- and welcome to the Forums! Perhaps you've seen my posts (latest one this afternoon) on
this thread. This is a fairly small trailer. In spite of the obvious stylishness, the corner master bed is small unless one partner is closer to 5' tall. Putting the dinette down as a bed for two just works on small children. Your two children are at the age where this would be beyond you about the time you got the trailer. Depreciation on this small but high priced trailer will be definite, though the attractiveness will result in better resale compared to a 19' Safari Bambi for instance. I'm not sure the tow vehicle listed in your profile would really be up to the task -- we have a member using a Touareg for such a large (actually larger) trailer and he is vastly over-reaching on safety. Do I recall that the owners manual even recommends against using weight distribution gear? It even looks small if you put a Cayenne/Touareg up against a 10' tall Airstream.
It might be a case of needing to walk before you run. Take it easy -- do it if you will. But I'd recommend something more like a 1/2-ton Suburban or a Lincoln Navigator to tow a 19' Airstream.
I love my '06 for the long term and rent inside storage to maintain it for the best. We've had a member from Minnetonka get rather stumped on finding off-site storage for his Airstream.
Best wishes in your quest!
