This is the point where a pilot would be asking, "What is my current and/or
planned "mission profile" and how well does my current equipment fit that
If the Airstream still meets your needs, then maybe you should keep it.
(It is a beauty! )
However, if you would now like to travel farther, with a smaller tow
vehicle and less fuel expense, then maybe it might make sense to
make a change.
Only you will likely know your wants, needs, and constraints.
When our family was younger, we had V8-powered custom vans that we
used to haul Boy Scouts to events, kids & friends to soccer games and
school events, travel to Colorado snow skiing trips, etc. We also had a
StarCraft Starmaster21 pop-up.
We the kids left home, we sold
our pop-up, drove minivans for a while,
and eventually downsized to smaller SUVs. At family gatherings, my kids
still often talk about the fun had on many trips in that pop-up camper.
When my son got a pop-up for his young family and we realized that we
were approaching retirement, my wife said "I really enjoyed camping and
would like to camp again but, I really don't want to put up with some of
the drawbacks of a pop-up camper. Isn't there any kind of enclosed
trailer that we could pull with our Honda CRV
She hoped to take grandkids on camping trips, take some trips to both
coasts, and revisit some of our favorite destinations from years past.
The limitations of our tow vehicle, the amount of sleeping space, and
our desire not to let fuel costs put a damper on our trip spontaneity
and travel adventures were just some of the considerations that led
to our current trailer.
In the future, our "mission profile" (and consequently our trailer and
tow vehicle) may change again? Who knows?
IMHO - You should own the equipment that provides you the most
happiness and best suits your current and planned travel wants/needs.
Just my 2 cents worth. As always, YMMV.
Best of luck with your decision!
