This is my first post on the site. So this is an introduction/rant.
To start, I will give you some background.
I just picked up a used 2006 Nissan Titan. It looked great on the lot. Had nice features, nice interior, only 28,000 miles, the works.. I was sold, so I bought it. Ive been using it as a daily driver/work truck for the past couple weeks, no problems. This past weekend (Saturday) was the first time I really used it for work. I pulled behind the shop happy as could be, I get to use my new truck and put it to work. So with a big smile and full of "new truck" pride, I stood there and watched them load a full load of gravel in the bed (roughly 3k I would estimate). Its loaded, so I get in and take off on my way to the jobsite. Everythings going great, then I see a red light up ahead. I think nothing of it, I hit the breaks. The truck didnt want to stop (It actually felt like it wasnt going to) but sure enough it did. I didnt know what to think of this, but I decide to continue over to the site. The light turns green, so I accelerate. The truck feels like its going to pull a damn wheelie

! All of the weight is transfered to the back and the truck sluggishly accelerates. I am feeling every little crack in the road like its a speedbump. I started to think this was normal, and I just wasnt used to the truck yet, WRONG! It does this all the way over to the site. I pull in with a frown and immeadiatly hop out to inspect. The front wheels were grey from all the brake dust! And when I stepped back and looked the front end was sitting about 8 inches higher then the rear. I lay down under it and the read shocks are bottomed out

! I pull it over and they begin to unload it, as they unload, it slowly starts to rise back up. When they are done it is still sitting low, but now AS low as when it was loaded. I still dont know what to think
After I leave the site to go home, I am still felling the bumps BAD, but not as bad as when loaded. The truck is still as sluggish as when loaded and the weight still feels transfered towards the back. I am thinking "WTF!?"
Now it is Tuesday and the truck is still sitting low and hitting every bump like a brick wall. The sluggishness when accelerating is gone, but it still feels like its leaning back. I am NOT IMPRESSED with this "great new truck" I just bought. We have another job Thursday that required moving pebbles, and I will be taking my 94 6.5T (previous truck) because I know I can rely on it to haul. Until I figure out whats wrong with it, It will strictly be used as a grocery runner and small errand vehicle.
It sucks buying a "new" truck that is supposed to be great and then not even being able to use it. I dont have much money so when I buy something I need it to work, and so far this hasnt.
Any help would be much appreciated
