New truck last year 2010 2500 Mega Frt GAWR 5500 Rear GAWR 6010 GVWR9600 GCWR 25,400 Rear hitch rated at 12,500 What numbers are the best to use in choosing 5th wheel or TT toyhauler. Have been looking at keystone Fuzion 295 2011 Hitch weight 1280 Ship wt. 7,288 carry cap. 4,155or the forest river 29ckv Hitch weight 1304 Ship wt 7329 and GVWR 11464 and Carry cap 4135 these are both TT's Have not been able to find a 5th wheel toyhauler other than a Thor 35 footer but belive it to be to larger for the 2500. Have no spec on it yet. Also with a tow behind of the size above would you reccomend a equalizer hitch.
