i'm sold on the 6 wheel drive ..6-wheelers. They can go through more mud than my 4x4--650 kalasocki , I also aways take my 4x4 -4wheeler just in case the 6- wheeler wont make it but so far the 6-wheelers has found a way to get to the bay,,,THE 6- WHEELER RIDES REALSMOOTH, & carries lots of people & dogs & hogs. THEY ARE GREAT.I tried the trailer thang and it's so hard on your atv plulling a loaded trailer through and getting stuck all the time and for get pulling a trailer around a wet grain field, mud will clog the tires up and lock the wheels where they wont turn.too muddy in my country to pull a trailer.might work better in rocky country.
