you said you were looking at a big bear 2x4 right, well i own a 4x4 and love it it has infinite low end and a decent top end (slower than my klt) but it would probably be good for you, it easly tows pretty much anything
hope this helps

 

yeah jarods right, i have ridden his and it has tons of low end, it gear on gear so no belt to slip, auto clutch, o and it would be big enough. top speed is decent about 45mph it would be good for you i think. [img]i/expressions/face-icon-small-smile.gif[/img]
