Which draw bar do you go with and what size ball fits most inboard direct drive trailers?

Valley, Draw Tite, etc are all good quality. Find the one you like the looks of the best. REMEMBER that you will have to look at the exact model number for your truck...not just any one that have on the showroom display. Each model looks different. Some are more visible than other.

You also need to ask if new holes need to be drilled...if you don't want to buy a big bit.

All the balls for these types of trailers should be 2"

PS - let us know if you find any that aren't made in China.
