I've noticed we have some (a minority) of Chevrolet Silverado HD models listed as the model name 'Silverado HD', while a majority of others have 'HD', '2500HD', '3500/3500HD', etc. in the extra info section. Should I put them all as model name Silverado with the 'HD' in extra info, or should I go through and change the model name on the others to 'Silverado HD' and 'Sierra HD' bring them more in line with how the Ford and Ram pickups are listed (F-150 vs. F-Series Super Duty/Ram 1500 vs. Ram Heavy Duty)?

I know there was a discussion about this a few years ago, but I don't remember what conclusion was reached, if any.
