I have read a lot of posts on here and it seems like most of you prefer CoachNet. Does it also cover the towing vehicle? Without the trailer? I don't want to have to carry AAA and CoachNet. My insurance has towing coverage up to $500. If I purchase CoachNet should I drop the towing coverage on my insurance? I am also paying for $100,000 in vacation liability in case someone gets hurt in our trailer while we are at the campground. Do I need that? How much liability would you suggest we have on the truck in case (God forbid) the trailer comes loose?
