A big welcome and Congrats on your new Airstream...WOW 7000 miles - that is what I call falling head over heals in ALUMINUM LOVE
I would love to make that trip one day - can't wait to visit California.
We have a 22' and use the reese and use a sway bar - it does make a difference - but you can still feel the push of air - it is physic. But we find if you are away of the trucks coming up along side to just push the gas a bit and it seems to compensate.
We even use the sway bar on our little 19' vintage and without we notice a big difference.
We are considering going to the dual cam system - just because we can.
You will have lots of fun with your Bambi - happy trails....see you down the line...
