Gabriel,
Be advised, that 4x2 is only rated for 1000 lbs. towing capacity. That INCLUDES the weight of the trailer. You will have to buy the crossbars, or order them from the dealer, to complete the roof rack system, only the side rails are included with the original equipment. If you want to increase the towing capacity to something more realistic (2k lbs) then you need to get the 2.4L engine and the towing package. This DOES NOT include the hitch. I lived in Michigan for 45 years. I cannot remember a single year since I got my drivers license that I did not find 4x4 useful. Whether you NEED it or not is a question only you can answer. The 4x2 will go through snow fine, if you know the vehicles limitations. If you drive one of the 4x4 models you will find most snow storms to be a joke. You will be WISHING it would snow.
