Looking to do some up grades on my 03' dually. It bottoms out a lot when loaded with my Boss 9'-2" "V" plow, (about 950 pounds),two tons of rocksalt i the rear spreader (spreader is 9' long and weighs in at 900 pounds empty). Looking at the extreme duty hub conversion from EMS Offroad, to help aid with the added plow weight and also all the wear and tear front axle joints (replaced five, truck only has 42,000 miles on it!!! ). Also, looking at 19. 5" tires and wheels from Ricksons - a lot of money. The truck is also used as my fertilizer hauler, with atleast 80 fifty pound backs of fertilizer, 4,000 pounds plus pull my 10,00 pound equipment trailer. Just wondering on your thoughts on the upgrades and any other suggestions Maybe time to move up to a 4500 or 5500 CC ??? Just don't like the idea of new payments. Thanks, Frank
