My doctor had one, used it to rock crawl. He got married and that ended the rock crawling. He took it to the body shop because he saw some rust underneath, they told him the entire frame was rusted out and it wasn't worth fixing. He traded it back in to Ford for another Raptor, he loves them. I think they gave him $38K on the trade in, he lives in Easton PA so I don't know if he ever had the undercarriage washed.
