Geoff & Tony...especially if both of these are SuperDuty cars, both your friends should grab the PHS documents now if they haven't already...just in case something changes and the PHS service not available any longer?.
Sure, it may sound next to impossible now but considering some of the documenting service situations of late, a heavy lawsuit or two could put a stop to any of these services we now take for granted and a fella'd sure be kicking themselves later if they missed out?!.
