Regarding the video, I think it would have to have some serious performance enhancements to do what the video shows.
Well maybe this is a good place to make an announcement that I bought a 2021 Ram Crew Cab 4x4 2500 Cummins Turbo Diesel yesterday.
When I joined this website and got into off-roading in 2018, I was surprised with what kind of equipment people buy to come to the dunes, like big trucks and toy haulers. I had my 2007 Dodge Ram 1500, and my small flat bed trailer, and that was it. I didn't know anything about diesels, and the name Mega Desert Diesel really caught my attention. I even saw this huge customized diesel pickup one day on the I10 (it may have been a 5500), and I half-jokingly said to myself "Maybe THAT is the Mega Desert Diesel!!?".
Anyway, even though this purchase was not all about off-roading, now I have my 2500 diesel. And driving it home from the dealer last night, even though I wasn't trying to push it, I felt that turbo power.
