i am a firm believer in working with what you have, i personally love all the factory srt parts and accessories and try to use as much of them as possible.
i would do the srt treatment, but hold off on the badges.
here is an 04/05 regular cab v6 ram that received the srt-10 treatment. as in complete body kit, interior, suspension and exhaust. he even put the srt dana 60 in it.
the truck looks badass, has lower insurance, increased mileage and no-one knows it's not a 10...
