I know I'm a little behind on this site, but someone has to work.

Anyway, you definately want a Hemi if you plan to tow heavy trailers. This year I towed my 5782# loaded 27' travel trailer to Colorado with my 4.7L Commander. Big mistake. Got 8.1mpg headed west and 9.2 headed east. It was a battle to keep it cool, because the motor wanted to spin 5000 rpm's the whole way there.
