Looking to buy a 1500. Right now its between a 2wd crewcab with the 4.7 st model 49k miles for $19777. Or a v6 2wd crew cab with canopy st model with 47k for $17899. Im leaning torward the v8 but am unsure .any input would be greatly appreciated! And for the main reason I started this thread, I was wondering how hard the smart key is to install on a base level 1500 st, i did a search and couldnt find anything about it.
