Thinking about buying a "newer" truck - any advice?

Seen the cylinder heads on F150's mentioned. Know of a few people who have mega-mile 150's and never had a problem with the plugs/heads so..........
Did not read the entire thread so don't know about how much $$ you are looking at spending. Have always been a Ford truck person....but I bought an 02 2500 Cheby with a Duramax & 5 speed Allison. Best truck I have ever owned. Broke the trans....all diesel trans are pricey but buddy did it for parts alone so it was a tick over 3k. $1400 or so for a real good t/c. Truck runs very well. Has the typical LB7 injector woes so it puffs a bit....Tows with a vengeance. Great truck. And was what I wanted, option wise. Cloth seats, no power windows etc. Good luck on your hunt....
