5 owners? 127K miles? It's possible, but barring a thorough mechanic's clean bill of health, I'd keep looking. There are a LOT of used F150s in Texas to choose from.

Those 4.6l v8 triton engines have issues with the spark plugs coming loose. The 5.4l have even more problems, from timing tensioners leaking, cam phasers, rocker arms and spark plugs seizing requiring special tools to remove the plugs. Good luck!

I would go with a early 2000 tundra with the 4.7L those are virtually bulletproof. 

First one has too many owners 

Second one has the horrible 5.4 3 valve V8

Agree with, @Glen_stet, five owners is wild and gives me pause. I do like the honest pictures (dents, missing speaker grill). I also, like the overall idea of the truck, 8 cyl and RWD is the way to go. 

About the second truck, seems better. A 20 yo truck for 6K, seems reasonable, going with @Glen_stet, mechanic clean bill of health. Even just to see if its been in a crash. Check em both out, drive it around the block, request you want to see the car cold, bring a flashlight, look around. The more "practice" looking at cars, will start to get the hang of it and in time may start to see signs of things being off (gaps, over spray, too clean/too dirty engine oil).

Scotty has let us know that Carfax may not catch crashes, in other words a clean Carfax is to be taken with a grain of salt. Consider your budget. Is there enough to cover an uexpected repair? As a daily driver, what is a daily driver? Driving 100 miles each way? That may be a tall order. Going back to the Carfax, 10 records for a 20 year old car, a well maintained car should go in every 5K, 10 records seems low. Im contractidicting myself by writing Carfax cant be trusted, and then saying there are too few records.

Check comparable vehicles in the area, if the price is similar, then it is. Check prices 100 miles away for comparison. Of course, bring the truck to a mechnic to check out.
