I'm interested in purchasing some sliders for my 4runner, I'm an avid offroader, but as this truck is also my DD, I'm concered about frame integrety as far as rust in concerned. I have an 84 PU as a farmtruck/beater with a bad case of body rot even though I live in salt free south louisiana. After my roomate and fellow offroader had his sliders welded on I was concerned about the bear metal between the slider mount and the frame. Should this be a cause for concern? Or would welding all the way around the mount discourage rust from taking hold between the two pieces of metal? Perhaps I'm being paranoid, but I don't want to loose another Toyota due to rust. Especially one as cherry as my 4runner.
