I appreciate it Rick, and I value all opinions. Most of the people I have been talking to on the Diesel forums, also have a long history with gassers prior. There are also people trying to detour me from getting a diesel for the same reasons you say.
A lot depends on how much we plan to tow down the road. I just know how my 5.3 handles our current 5,600lb trailer, and expect the 6.0 will be the same with a 8-9000lb 5th wheel, suck city up hills and gass suckage.
