Welcome!
Not sure I understand the question. Are you concerned with having enough power to tow "that little" up a hill or is it related to having the trailer lower and behind?
Thoughts are you are a little concerned that this 3.0 liter engine does not have the "snot" to pull anything. Do you think a Hemi V8 has enough "snot"?
If you do, then remember that this little diesel is the "engine that could". It has a tiny bit MORE pulling torque than the typical Hemi V8 they use in these pickups.
