Click the "Roadside Assistance" link at the top of this page.
Then click "Find a Plan" link near the top of the newly opened page.
Select whichever plan you want from the drop down, and it will tell you what's covered and what's not.
The towables versus motorized coverage change happened a while ago.
I renewed 2 weeks ago for 5 years, and am still waiting for the new plastic membership cards.
I'm trying to be patient. If they're a no show in another 2 weeks, I'll follow up then.
Good luck with your other questions.
