My son kept a Mopar from getting scrapped

Where's the damage?

Those are good trucks, although the 3.9 is hit and miss on power.
I've had some almost as powerful as the 5.2, others only marginally better than the 2.5.

Be aware that the window winders on quad cabs are different than the others.
Instead of a scissor regulator they have cables.
The nylon guides on the end of the tracks like to shatter, making for a spectacular abrupt window lowering, complete with dramatic sound effects.
You'll likely think someone shot it out.

I've replaced the winders so many times on my mom's 03 that I have wood braces already made up for next time and have drilled holes in the door shell for better access to the screws.
You'll likely lose some skin on the insides of your forearms the first few times.

Also be aware they like to eat tensioner pulleys and sometimes water pumps.
I also cut the tang off the top hose water neck so I can get it out without taking off the whole AC bracket.....and the heater cores rust out because they are oddly positioned height wise to the rest of the system. Dash removal required to replace.

Other than those points, which I consider somewhat minor in the grand scheme, very dependable.

Mine has a home until one of us dies.
...and if it dies first chances are likely for a resurrection.
