hey guys i just basically inherited a 2007 sierra classic. its got a 4.3L v6 and it definately doesnt have suspension for major towing. its got around 18k miles and gets average like 16 mpg. should i trade it in for a nicer 08 silverado/sierra? ill probably be pulling a 5x12 trailer with 2 WB's and other equip. do you think the 200 hp and lack of suspension could pull that size trailer with equip?
