The Nissan Path

So i installed the airlift 1000 earlier in the week on my 07 LE. Have the bags set at 12psi right now and no leaks. Im gonna be towing a 6x12 trailer loaded with 4 quads, gas cans,and 3 sets of spare tires. The back of the truck will be loaded with quad helmets,3 days of food/drinks/clothing, a small set of tools and a total of 4 people. did I mention driving 500 miles one way to go quading? What psi would you set the rear bags at? I was thinking 25psi would be good. Its my first trip in the path since i bought it last month and hopefully I dont run into any problems. I did a oil change, checked the tire pressure/ aired up the spare just in case/ checked all fluids, brake pads are new as of last month. anything else im missing? I have to admit im kinda nervous since i just got the truck. I have no problem driving with a trailer. My dad has a 24ft. boat he tows with his sequoia that i have driven plenty of times. So hopefully all goes well and i make it back. Should have A LOT of pictures from when I leave to when I get back.

25 psi should be perfect.

a few pics. Cant really take many while your covered in mud or ripping throught the trails in 4th gear lol. Overall i was impressed with how the pathy handled the 450 mile trip there. I was averaging 13mpg towing considering it was nothing but hills thats fine by me. It was a dirt road up a hill where they required 4wd to get to the camp site i was staying at.
