Purchasing Advice

I have recently decided to upgrade to a crew cab truck from my Jeep TJ due to growing family needs. Having looked around in my area, a 2007 Titan LE stands out among several F-150s. I will include a link to the post at the end. I want to get a buyers inspection done on it by a local Midas, but what else do I look for that the average mechanic wouldn't catch? What are some of the common problems assocciated with the 2007 titan? It's sitting at roughly 126k miles and despite the number of miles it has, I'm looking for a vehicle that doesn't require a lot of maintenance since that is part of the reason I'm looking to upgrade from the Jeep. Thanks for any help.
