I bought my first RV and the original ball that the dealership put on my hitch mount started to get all gouged and torn up after a few trips. I was convinced that I needed to find a better piece of hardware. This one stands up. 2 years and going.

You can not find a better or higher quality ball on the market. I use this when hauling my dump trailer knowing that it will never be the weak link EVER!!!!

This is one HEAVY towball, no doubt it is capable of the 30,000 lbs. will haul any trailer out there!

I have tried to locate this exact hitch ball for several weeks. I own a bus and pull a 30' long, 14' high, stacker trailer that weighs in at 24,000 lbs. This is well built and very heavy duty machine finished hitch ball is exactly what I need. I was able to easily find it on etrailer's website.
