Good links fellas... THANKS!
I currently have three Cummins trucks (and have had many before... 25+/-).
Only had one Excursion... but loved everything about it.
Big decision now (if I proceed) is the trans and TCase.
Sticking with a built RE seems easiest, but I'll start asking the pros more questions.
SEEMS like the full Mopar drivetrain will make the most sense.
Heavy hauling... not really... other trucks for that.
Hard use... absolutely.
