Buying new truck but what truck is the better deal?

After getting so HD video of both trucks up and down and under all three the 15 with 118 on seems to look the best , the other two showed signs of rust covering the receiver so who knows what the rest of the truck looks like when the 15 is spotless just two years newer with a few more miles and a great maintenance record so I’m leaning towards it ... just have to get over the 10k in price difference ...
