Welcome, JenandJes. You will get a lot of good advice here, but some of it will leave you scratching your heads and wondering what's going on. Slow down, take a deep breath, and relax a bit.
Get the gross weight of the Airstreams you are thinking about. Figure 15% of that will be weight on the tongue. That's a bit high, but gives you a couple of pounds of leeway. The gross weight is the total weight the tow vehicle will have to pull and stop. The tow vehicle will have a Gross Combined Weight Rating. Subtract the weight of the tow vehicle (fully fueled and loaded with yourselves and your stuff) from that GCWR and you have the maximum the trailer can weigh. If that number is more than the Gross Weight of the Airstream you are okay.
"Have you considered an Airstream diesel pusher MH instead of an Airstream TT? You will not need to worry about tow weight restrictions. Then you can tow any vehicle you want." Well, not quite. Gross Combined Weight Rating will be a factor here.
Do a bit more research before you start shopping. As others have said, an Airstream is not a large coach, and if you are going to be full-timing, you WILL have days where you are stuck inside.
