Here the truck with the trailer it a 2wd diesel

Again, some more in depth on the trans situation. Is it built or no?

otherwise, lift pump is your first purchase if the trans isn't built. Studs could be but you can probably get away with the pump for now.

my tran is not built it has a shift kit and valve body drill out with a HD tq convertor.my truck only has 90000 miles on the truck.

Determine what you can do to beef your trans up for towing and street.

this tranny has been gone through at a tranny shop plus I run 100% syn mobile 1 tranny fluid in it.You also asked about a tuner i run a smarty jr pod set on SW3 at 99% pod
All my work has been done my a very good diesel mechanic in are area he has thousands of customer. this truck runs strong and even pulls stronger. he build to your needs. I just went a little over board

What kind of filtration are you using for your rebuild? Want to protect it with a 2 or 3 micron filter!

for now it the stock system. Think about if it wasn't good they would not use it .plus I change my fuel filter ever oil change. filters are cheap
