Shouldn't be a problem especially if the trailer has brakes. Won't be the fastest rig on the road but should pull and more importantly stop the Z7. Just make sure the rig totally loaded with gear, gas and fuel isn't over the towing capacity of the Nissan.
I have an 882 with brakes that I towed with a 143 HP 2004 Xterra and it struggled a bit. I recently purchased a 261 HP 2011 Xterra PRO 4X with 4 wheel disk, transmission oil cooler and full tow package. I can't tell the boat is there, no issues stopping as well. I put a pic in my library if you want to check it out.
