It looked in perfect condition, had all the features. Well it has been one year since I bought it. The truth of the matter is it has more miles being on a tow truck than we put on it. I am stuck with a 30 foot lemon, making payments hoping the next person who buys it has less problems than I had. Now if you are sure you want one, I have diesel it stinks and they are loud when driving them.
