New here

Hey everyone first let me start off by saying that if this is in the wrong section I apologize. Other than that pretty much I just got back from AIT, I'm a 31B/Military Police (Glorified hall monitor right?.) And I'm looking for a Toyota truck I have always wanted one.

Pretty much I'm looking to spend about 7K give or take and here's the list of what I'm looking for in the truck and can you let me know if thats a realistic goal ?

Upper 90's
4x4
Ext. Cab
Blue/Black/Green/White
Manual Transmission
Under 150k Miles
Can be completely actually it would be nice
No to extremely minimal rust

And then does anyone know the difference to the TRD and SR5 packages thanks.

Looking forward to learning alot and not to mention getting out of the Honda game lol

Would something like this be worth it?
What are some things to look for in these truck besides rusting frames and the usual vehicle stuff
My dad had one with over 500k so I know miles really shouldn't matter ha.
