I think it depends on the weight you have to pull. I've heard however that they are quite good for pulling with, I had a look at one but ended up getting an Isuzu Trooper which I think are one of the best 4X4's for pulling a trailer.
I had one a couple of years ago, pulls a 505 and two 500Kg horses with ease. Very nice to drive and you would never know you had a trailer on. Have had a few 4WD's and it was probably my fave one, have a shogun now, but have yet to tow with it.
The answer is yes........but they are a little light so be careful on overuns downhill. You should be able to go on the Nissan site and check the authorised towing weight.
Yup, I have one, and it's brilliant, I tow a 505, with two full sized Highlands with no probs, and I live on Dartmoor, so have to up and down some steep hills.
