looking into this, there's seemingly a lot lower profile options to achieve similar results...(ahem, land cruiser *cough*). The engine options don't really inspire long term (and austere) reliability IMO. The SRT V8 being among the options on the webpage. I don't own a dodge and God willing never will (commence flaming). Some of their older Cummins were bulletproof (see 900k/million miler cockroach ~'96 MY 2500/3500), BUT this AIN'T that.
TLDR - I see quite the tempting loot drop after minor creativity.
