Several Sites, but again you have to always be cautious and use your own descretion. RVonliine. com, RVclearinghouse.com, PPL, and others. Right here in this forum there's units for sale. Depends on what you are looking for. Heck even mine is for sale but I really don't want to sell it, cause I'd just have to buy another and got this one the way I want it. Too many memories with it, like it runs off and leaves the wife at the Flying J, LOL only kidding. Many units are available out there. Look around and test drive any and all and then make up your mind. Always be aware of what MaMa likes about the kitchen, This is vital. Most of us drive Class A and have worked our way up from campers or Class C. Not a great $ difference when buying used, and in my opinion makes a better family vehicle. Also you can buy a better quality unit forless $ if it's a year or 2 older then others. That again is only my opinion, I'm sure others will disagree and for sure that their right to do so. No matter what you do, stay with the forum and good Luck. You have any questions just ask, you'll be surprised how many pro and con answers you can get.
