Hi Trey: You mention you have kids. Will they be travelling with you. How many and how old. Keep that in mind when you look at possible choices. The more you have and the larger they are, the more RV you will need. Also, I am in the group that doesn't think you can buy a reliable RV in the $15K range. It will be older and I would figure on leaks (roof, sides, engine, etc), brakes, tires, shock, and so much more. The repair and maintenance costs will climb higher with every mile. My suggestion is to continue tent camping until you have more $ saved and then look again. That is what I did 15 years ago. Some of the readers suggest looking, asking, searching, haggling, etc. It might work if you have lots of time but I would like to hear from RVnet readers who have actually gotten a $15K RV and how they did it. Also, what problems they have encountered along the way. Whatever happens, good luck and safe travel.
