January 2017 my fiance and I purchased a 2007 f150 from walser. March 2017 (2 months!) The rear differential goes out. I called walser and they were not willing to help at all. The only offer was brining the truck in and they would send it to their repair people (which costed me $1,200). Fast forward to march 2018 (current) and the rear differential is going out again. Once again....no help offered. Their first "core value" under their mission is to "do the right thing". Thanks for doing nothing.
