Ok guys... Here is what happened today... I went to look at both trucks and was able to drive both trucks. The rides, performance, etc... seemed the same. The one thing the really impressed me was how "tight" both trucks were, no rattles, shakes, etc... really different from my F150.
Anyway, I popped the air top cleaner and on both trucks there seemed to be some dust under the air filter. Not much but some...
To make a long story short I ended up leaving a deposit with the fella from the construction company. The state inspection expires in October and the interior, while in good shape, was somewhat dirty. He is taking the truck on Tuesday to get a fresh state inspection and have it detailed. The fella said the only problem he has ever had with the truck were the batteries. The two batteries in the truck now are less than a year old. The truck only has 109,000 miles and I was able to pick it up for $9,400.
