A lot of people over-spec trucks. This can be an advantage if you decide to grow down the road in a couple years. If you plan to buy used, and sell it for another newer truck and don't tow more than 6K regularly, a half ton will be fine. Today's 1500 series trucks can easily handle everyday use and abuse, and are a lot more economical than a 2500 or heavier truck. My old Dodge Spirit (2.5L I4 3 speed auto) pulled my old utility trailer with aplomb. It had 380,000miles (625,000kms) on it before the rockers rotted through. Besides needing a new head gasket every 50K miles, it ran like a champ otherwise pulling up to 1500lbs, and carrying two passengers. I even used it to carry firewood to the trailer when I had it parked seasonally; total weight pulled and in the car pushed 3000lbs. It was slow, yes, but at 24mpg average economy (10.2L/100km) throughout it's time with me. Its a shame that I've outgrown that small trailer and upgraded to a '90 C1500, which did a great job during the time I had it. 1500 series trucks can carry up to one ton of payload, and tow upwards of 10K. I wouldn't tow 10+K with a half ton just for suspension and driveability reasons, but for up to 6K, it'll do fine.
