New guy with questions

[kevindp]

Another new guy looking for some answers on some probably basic questions. This is my first diesel purchase and I am looking to make it last a while. To start off I have a 2005 F350 CC/LB SRW FX4 I bought used at 120,000. It has had some after-market work done. I know it had the Head bolt to stud replacement done, I’m guessing a 4" lift, the dealer was not sure on the manufacture, an exhaust upgrade, it also came with some almost new BFG Mud-Terrain T/A KM2 that are 35 / 12.50 / 18's. These are D rated tires that I leave at 50 psi. I think those are all the changes. Ill post again if I remember anything else.

So to my first question. How does this lift and tires change my payload capacity and towing ability? I know the E rated tires are the preferred ply for large towing but the tires on there now are almost new and would hate to spend that kind of money right off the bat if I don’t have to. Those tires are rated at 2910@50 psi. Should I bite to bullet and do the swap or am I fine pulling heavy loads?

For my next question. I live in SE Washington; does anyone know any good Diesel shops in that area? I would like to take it in and have it walked through to see what all has been done and what looks like it needs. Like I said above I plan on having this truck for a long time and would like any info on basic stuff I can do to insure the longevity of this truck. Any helpful info on that would be much appreciated. I am new to the diesel game and can use the help.
