... is there any big difference between towing an Airstream and a Fiver. ...
I've towed both, as a matter of fact.
The Airstream was a 31 foot'er. It was the last bumper hitch towable. Not because it towed bad, it towed better than any other towable we owned.
I started towing it with a standard, load equalizing hitch, no problemo. I picked up some "parts" of a combo load equalizing & anti sway setup, got everything together & towed with it. That got rid of some if not all of the "tail twitching".
The Airstream is just great as a towable. As a matter of fact, I purposely didn't dump the holding tanks, which were in the rear, & towed home. I figured the added weight in the rear would bring the ugly'ness out if there was any ... nada.
We transitioned to a 5th wheel, 27', with slide out. Really roomy as compared to the Airstream. Towing ... no comparison. It's not even the same game. When you hit bumps with the towable, you get that "rocking" from front to back with the towable, nada with the 5th wheel. Side winds aren't a problem anymore. The dynamics of the side wind on the truck & trailer is way different. More of a "white knuckle" experience on the stronger gusts.
My opinion ... stay with the 5th wheel. Change brands/floor plans, whatever but keep the 5th wheel.
