I drive my 46 2-ton in town and don't have any issues. It is just a foot longer than my 2011 and that is only due to someone extending the frame behind the rear wheels a few feet. It does have a little longer wheel base, but it really isn't bad. I have had about 6500 lbs. on the back also. It road nice, but made me realize the engine is really tired.
Keep it big, once you drive it and get used to it, it's not that bad.... Of course unless your used to driving a smart car all the time. If that's the case I will come and take this truck off your hands!
