I'm one model down, Limited with the 5.7 Hemi plus AWD. Only two reasons I didn't get an SRT8 - 1: too much more $$$, and 2: Tow rating is very low, plus you have to relocate the exhaust to install a hitch. As for TBSS vs. Hemi Jeep - I ran jaSSon in his TBSS and was nose to nose with him until halfway to the next light, when he started pulling. I have no doubt that an SRT8 would have a slight advantage over the TBSS.
