You really do not see ST's much anymore. The base model on most dealer lots will be the SXT. The SXT has a base package with things like power doors, locks, mirrors, and heated mirrors. It will have cruise and a CD player. The resale value of an SXT is much better then an ST even thought you will pay about the same for both. Gas HD Rams have a really bad resale and if you go to a 3500 SRW it will only get worse because the cost per mile to operate is not very good. HD Ram sales are around 90% plus in favor of the oil burners. GMC/Chevy favors the gassers more then Ram or Ford. If you want a truck you won't be stuck with for life and gas is your thing I would ponder the GM's. They will hold their value much better. Good luck, hopefully you make a ton of money and can throw down for a beastly 6.7 big C under the hood.
