"Now the process begins to trade in or sell my sedan, buy an F-150 to haul my new travel trailer, then buy the trailer." Triple

My son just bought a 65 thousand dollar Tundra, it's a sweet vehicle but I had to co-sign...isn't that why God made dads? Anyway, when I asked him about his old truck he said he wanted to sell it and I asked him why not trade it in as selling a vehicle is a big hassle, and I speak from experience. We asked the salesman about a trade in and he told us that he could probably get a better deal through Carmax than through them. So maybe you could look into that.
