I've been looking into this as well. I found this link:
http://www.myautomotivehookup.com/Ho...Insurance.html and will give them a call tomorrow to find out the details. Based on what it says on the website, it isn't the greatest deal with a $500/day premium and $5,000 deductible for only $25,000 in coverage. Seems like they have some multiple day coverage that would be better value. The coverage is through a company called Ermis (i've personally never heard of them before).
