We are planning a trip out west this fall including spending the winter in Florida. We have a 2004 All American Sport 5er toyhauler. I am the second owner and most of the original warranty has expired. I need a recommmendation on what extended warranty to purchase, if any. There are several companies to choose from such as Good Sam, Infinity, ect. Who do you feel has the best coverage while still remaining affordable. Looking forward to your comments. Thank you.
