late 99 f250 7.3 clutch?

[99f2502wd]

I just bought a 99 f250 4door 2wd 7.3 with 151,000 miles one owner,never pulled anything bigger than a yard trailer.I put 4" turbo back ,airaid intake,ts 6 pos chip.I pull a 10,000 rv and on my first trip this weekend the clutch started slipping on up hill pulls.What year did ford put the dual mass flywheel in these trucks,and do I need a super heavy duty clutch just to pull a ultralight rv,Thanks

99 6 speed was a solid flywheel. its not the ultra lite trailer its the increased power the stock clutch wasnt designed to hold

Which would be better ceramic or organic,I have found each for 800 ft lbs and around 350 hp for the same price.

I believe ceramic will be very grabby.. if that makes sense.
