My operating assumption based on initial dealer convos is that there is no loss of warranty when the dealer does it and then certifies the vehicle, used or new, hence the urgency of the post and current need for a reliable kit. I see a similar thread further down and apologize for the duplication for those following both. I will look into the Ready Lift lead, thanks. And yes, personal preference, just like color, rims, stereo, trim level, etc. I respect the look of the level, I leveled my 2004, and lifted my 2013 4 inches. I just like the look of lifted trucks. Full disclosure, only real life example of true need was getting through roads flooded by Hurricane Florence, so sure, it's overkill for a grocery getter, but I've spent $4k on dumber things before and will again. Thanks for the replies.
