You'd be hard pressed to find a 2720 with under 450# tongue wt, fully loaded, ready to camp. Mine is over 500#.
You must subtract your Nissan's curb weight, passengers, cargo and fuel to determine the maximum trailer weight that you can tow..
I show the curb wt as 4,480#. If you add 400# for passengers and 320# for cargo, that leaves you with 3200# MAXIMUM for the
fully loaded trailer and fuel.
My 2720 weighs close to 4000# fully loaded.
I think that you may do more harm than good to your Nissan Quest towing most any TM. It's not a good idea to tow @ maximum capacity and it's a bad idea to tow over max......
