My truck had a curt hitch installed when i bought it..but ive recently bought a malibu ski boat that weighs everybit of 3500 lbs with the trailer, if not more than that, which ive towed probably 5 times...its definately at the threshold of weight but fornuately the boat ramp is only a mile or two from my house.. The sketchy part is pulling that biothch out of the water up the ramp...my clutch smokes everytime...i got a feeling im gonnna need a new clutch before this summer.
