I feel like the front bumper/fascia must be where Lexus takes up all the tolerance between body/frame on these trucks. Your install sounds basically the same as mine. I thought getting everything trimmed and aligned was a giant pain in the ass because my GX had a minor collision from the previous owner but maybe not. My bumper is straight on the the frame but getting the fascia trimmed/fitted around it took basically all day.The Victory Blitz bumper... ugh...:
