If it were me I would get one the hitch and at least one sway bar. I have a Pro Series round bar Weight Distribution system with the 550lb round rated bars. When we purchased our new camper a few weeks ago I knew I needed 1,000 lb bars.
I was about to order the replacement bars off of E-Trailer about the time camping world called me to come pick up the trailer. I had to scramble a bit but found that Harbor Freight had an entire WD system with 1,000 lb bars. It looked very much like my ProSeries.
I got my 20% off coupon and headed to Harbor Freight. I think I paid $180ish OTD for my hitch.
I was right, the “Haul Master” hitch is the EXACT same hitch as a round bar ProSeries hitch. The shanks are the same, the bolts are the same. The only difference is the HaulMaster bolts didn’t have thread locking compound on them. Something easily fixed.
I mean Weld for Weld the same.
Oh Camping World even set it up for free for me (Which, of course, I had to reset when I got home)
HaulMaster for the Win. I even picked up their cheap sway bars...which are exactly the same as my Older Husky sway bars. LOL.
Here is a pic for comparison
Also, the bars are interchangeable. That will be super handy when I set up my ProSeries head for my future car hauler. 550 lb bars to get the car 1,000 lb bars on the way home.
I hope this helps some.
Thanks
