Yer welcome, brother.
Really, any TRUE Heavy Duty ELC will work great, but since you asked for brand preference, I like Chevron Delo ELC. It'll go for 8 years or 750k miles, or with the added extender, for 10 years and 1 million miles.
--------------------------------------------------------------------------------
The latest formulation of the Delo ELC has a maintenance-free change interval of 750K miles/8 years or 1M miles with an extender.
Fleetrite / Rotella ELC : The Rotella is the same exact stuff as the Fleetrite, just in different bottles and it's the best type of coolant to use. Just make sure you do a proper flush and use distilled water.
Zerez Extreme Duty (RED)...you can get it at Napa. It is already pre charged and doesn't require any monitoring or additives.

If you alread have back-flushed and refilled with ELC and just wanna top off, use the 50/50 mix. If refilling for the first time after a back-flush, use the concentrate.
Chevron Delo ELC is good for 8 years or 750,000 miles. Using the extender at around, but before 5 years or 500,000 miles extends the coolant to 10 years or 1 million miles.
