Last year I posted a ? about my clutch, after excessive backing to unload a 5th wheel my clutch was smoking & smelling. Has worked fine since then but I haven’t pulled until now. Yesterday I drove non stop on a170 mi trip, 120mi freeway & then 50mi on 2 lane up & down some long grades, after arriving I could smell something. I assume the clutch. Later after unloading I drove to town, 45 mi ea way. After returning as I got out I could smell something again. My concern is I have to return the 170mi home. I don’t think I have felt any slipping. If it starts slipping on a hill I should see the RPM go up quickly shouldn’t I? How should I handle the hills, I did most on the way down in 5th & once 4th? My biggest concern is getting the truck & 5th wheel home. Any special shifting or gear to use on the hills other than what I have said I used? Any chance of fire if it gets to hot?
