Its the easiest i've ever done. Hardest part was figuring out where to put the ballast.
I used a uni-bit for their grommet on the dust cover and everything looks factory.
Don't exactly know. The motors take away all the tongue weight then it has 100 gallons of fuel. It pulls great until it gets windy and will blow around. I pull 30k with this truck so it doesn't bother me with the boat.
