A lot of towing (wrecker & rollback) guys have been switching to V10's, including me. After 14 years of only diesels, I now have only V10's. Many guys I know in towing (who use Fords) will only buy a V10, and do not want a 6.0 or 6.4 at any price. That may change if the 6.7 proves to be reliable like a 7.3. I'm not getting my hopes up until I see the proof!
Not to mention what you posted at FTE today, that Ford is now going to offer the V10 in the F650/750 lineup, and is coming out with CNG and propane setups for the V10 in the F450/550 lineup.
Long live the V10!
