Good day all...currently have a '03 100th Anniversary in my Ford stable. As times change, and family requirements change it looks like I will be selling my 5.4 and stepping up to a Powerstroke. I am looking in the direction of an F-350 HD powerstroke (my most recent purchase is that of a 33', 11,300 (gross) travel trailer). However, I have heard that the 6.0 strokes have issues. I was informed of a head gasket and head bolt issue...any thoughts? Information is, as always, greatly appreciated.
