We went ahead and signed up for both - AAA & for $12 more, Good Sam... Seems the extra $12 wasn't much to at least be reasonably assured that if one couldn't make it or cover both the TW & trailer (as mentioned above in various places), we'd have an alternate resource available. Small price to pay.
