wanting to run 33s inthe future again

[heartsick]

ive been looking at a truck lately for a new addition its a 1994 chevy Silverado k2500 and I was wondering what size lift I should do and whether it should be a body or suspension lift to run 33" tires on the stock 16" rim and which would essentially be I guess easier since this will be my first lift kit install or which one will perform better and better ride since this will be a work truck and will end up offroad
