You need a positive response??? never worried about a warranty. It breaks you got to fix it and use all that money you saved by not buying a new one with a warranty. You can buy a lot of high end used units before DEF and computerized Cummins for $50,000 + or - and if you can pay for it never have a $1500 a month payment for 20 years. Can you imagine having a 1994 model and paying payments on it since new??? There is an American Tradition for sale around here right now for $29,500 that looks pretty nice------
