I got my new 2021 Ram 2500 Big Horn 4X4 Diesel 2 months ago after waiting 2 months after I ordered it from the Dealer. I had added the air suspension, 50 gal. fuel tank, the 12" touch screen display, Safety group B, Level B equipment group, and a new 20K 5th wheel hitch! So far I'm loving it! The air suspension really makes it ride smooth. More like a car than a big truck!
