Welcome to the neighborhood!
Be prepared to fix a few things. Go through the fluids and change them all, except the trany fluid if you can't have a maintenance history. With that many miles, it may be best to leave the tranny alone.
Check out the front suspension really well when you go to check it out. Have seller sit in driver seat while the truck is running and have him turn the steering wheel to full lock out both ways. When he/she does this watch the center link and idler and pitman arms, if they move up and down or "twist" AT ALL then they are due for replacing. Make sure to check all the fluids, obviously if the oil is black or anything like that, or if the tranny fluid is brown and smells burnt, or if the power steering and brake fluid smell burnt; all of this will point to the fact that the regular maintenance may have been neglected.
I would ask to have the seller either help you or go with you to a shop to jack up the front end and inspect the ball joints, etc. by jacking it up and while the wheels are off the ground, use a large "tank bar" (or something large enough to pry up on the lower control arm, if the ball joint at the bottom moves inside the control arm at all then they need replacing.
While you have each wheel off the ground, grab the tire at the top and bottom and push back and forth attempting to see if there is any play in the sheel up and down, if there is then the hub bearings need replaced. (the wheels should be able to move left to right.)
Finally, without a title, I would make sure and cover yourself any way you need to to make sure you don't wind up being stuck with a truck you can't legally do anything with, there are a LOT of scammers out there. I would also find out where the title is and contact the bank or whoever has it to make double sure it isn't a repaired or salvage title. Once you have it in hand it is too late to really be able to do anything about it.
