Dodge Nitro w/ the 4.0L

Im considering getting rid of my commander... i've searched the forums and only found info on the 3.7L...

I used to tow my boat w/ a 3.0 V6 Escape, it did ok... but not great (class 2), i got the hemi jeep, it does wonderful, great job. but my payment is killing me and the 13mpg daily commute to work and travel is killing me.

now doing research and running numbers, i can get 2 year newer nitro then my jeep w/ lower miles for around $100 less/month payment and jump from 13-14mpg to more like 18-19mpg.

the 3.7 im uninterested in its 210hp and 235tq, where as the 4.0 jumps up to 265hp and 285tq (or somewhere around there) and has 3.73 gears.

i cant do the 2 car thing bad situation for that, i still have to test drive it to see if i even like it at all, i love my jeep, if it only got the same mpg i would keep it, im not asking for a 20mpg plus vehicle to tow with that just not real life.

i do most of my driving for trips, i do alot of bowling tournies where i travel and haul balls and stuff in the back, summer time i have a dock slip and i dont tow that far, probably less than 5miles per week.
