I have an LB7 early Duramax engine and just replaced the injectors at 113k miles. The LLY is a much better design (injectors on outside of the valve cover) but don't have any knowledge of other issues. Always thought that (other than the early injector problem), the Duramax was an excellent engine. You would love the Allison transmission for pulling. It's a marriage made in heaven for RVers. My son-in-law had a Ford F250 6.0 and it was a lemon but as others have said it can be bulletproofed if you can get service records. The Dodge Cummins is a great engine (6 cyl.) with lots of history and great access for maint. Honestly though, with diesel prices so high you would probably be better off with a gas burner if you can find a good one. Just my opinion.
