Not much you need to look out for, IMHO. The alignment may need to be adjusted. But, this is an adjustment and not a defect. Fit and finish is excellent. Go over the vehicle visually at the dealer, before you buy. But, there are no major red flags to look out for. It's a VERY solid truck. There are thousands on the road now. The fact that this forum is SOOOOO boring, says a lot. It's a reliable and solid truck. I have 8k on my Pro4x diesel. I'd buy another 1 tomorrow. It's truly the best truck I've owned.
