Went to Dodge dealer to inquire about a new truck. wanted a 3500 srw 4x4 ho auto long bed 4 door white. Only one around is two states away. They have a dually,six speed 4x4 4 door white they can sell $2000 less then the other. Its a older built truck. Built on 01/03. Said thats why its less,before price increases. The auto is 3. 73 gear and dually is 4. 10. Cant decide! Also is there much differance in bed height between mine,see sig. and a 1998 dually and this 2003. Worried about goose neck height. Any advise guys. I can drive dully out for about $33,000. 3. 9%apr for 60 months and $2500 rebate,$1000 coupon got in mail and truck at invoice! Any suggestions?
