We did, on the Travco and the Suncruiser, and used them several times when we took the moho skiing in the Sierra. Not yet on the Sunstar. We've had it just a year and have had no plans to go near snow yet.
If you get them, practice putting them on first during the day when it's clear and dry. Then, when you think you're good at it, do it at night, in the dark, with someone randomly spraying you with a garden hose.
At least test them enough to make sure that they fit before you need them.
On the Travco, it was so lightly loaded in the back I could run the inside dual up on a 2x6 block to get the outside one off the ground to make it easier.
That didn't work on the Suncruiser, so I jacked it up with the tire changing jack we carried.
There's no thrill quite like chaining up in the slush along side a 2 lane highway like CA 168 on the way to China Peak.
