I went to Suresky truck center to buy a fisher x blade plow and he would not install one on my 2002 2500 with D-max. He told me that the weight of the x-blade(787lbs) exceeded the weight limit GM has put on the front end of the 2500 with D-max. If he put the xblade on my truck it would void the warranty from GM but he could put the 8ftHD plow(707)lbs. I cant believe 80 lbs difference would make or break the warranty! On the other hand assuming this info is accurate Im glad i was told the hard truth about it because I had several other people willing to put an x blade and even a 1000 lb Blizzard 810 plow on my apparently weak front end.I have a year left on my warranty and am planning to extend.Can anyone confirm this info, if so talk to me!
