Picked a 15 with 106 k miles.

Got it a few weeks ago from Sewell in Dallas. No issues, or so i thought. The service records don't indicate the valley pan repair, so I presume that's coming quickly. Had a new radiator installed 3 k mies ago. So far, I've ordered the Bilstein 6112 kit up front, and Dobison springs for the rear. Those are paired Bilstein 5160s. The plan is a 2/1 lifting. It's my daily driver, so nothing too wild was in the plan. I got some cheaper wheels. (BRONZE 9SIX9 -17×8.5 @ -10MM. I'm having Tamdem do the install. I've done a lot of suspension, but if I'm being honest, the KDSS intimidates me. I am still deciding on tire size. 265 70 or 285 70. I dont mind trimming and /or, heating liner. But prefer to not do the bmc, or cut the lower grill.portion. What are yalls thoughts?
