Question about hauling sled in a truck?

[crestview]

I had a short bed with a tool box and hauled a polaris with a 162 about 3 times last year. I had to replace the bolts holding the cables to the tailgate due to stress. With the tool box i had 2 lugs in the bed and 3 on the tailgate and about 2 and half feet haning out past the tailgate.
