It would be better if the trailer were a little lighter or I had 4.10 gearing (or both...), but it's getting the job done. Fuel economy takes a dramatic drop in the hilly areas since the 3.6L doesn't have the most generous torque curve.
Offroad it's fine. Once I'm in 4-low, it just hums along.
And yes, a lunette/pintle has a clunk factor. But it's so easy to hitch and use. Works great for us.
I've tried everything else and they all have more compromises so I've stuck with this simple arrangement. I'd prefer to use my Maxx Coupler but it's just such a pain to hitch-up with on uneven surfaces or on a hill (like my driveway); you have to line it up perfectly to couple.
