buying a new truck..motor question

[sn95gt19]

i know im probably going to get bashed for this but i am buying a dodge r/t for my daily driver/ tow vehicle, ive been looking and cant find any noticeable differences between the r/ts and the regular ones, is the only difference the rims.

did any other dakota's come with the 5.9 or just the r/t

if the 5.9 was an option on a regular dakota, im just going to get one of those and put the r/t rims on it.

thanks
