I read your post yesterday and was giving others a chance to answer as I’m not clear on what your asking. But if you need advise on a brand or way of knowing what size bars you need, I’ll give it a try. There are many hitch brands out there. They range from a couple hundred dollars to a couple thousand.
You need to know your GVW (gross vehicle weight) for your trailer, and your hitch weight. Once you decide on your brand you want, then that brand will usually have different size bars, and sometimes shanks, for that weight of a trailer.
I would suggest looking for a WDH that has a built in sway control. I recently purchased a Blue Ox and love it. Moderate price, easy set up, and performs very well. If you go up in size for a trailer, the bars are available to upgrade also, saving money rather than purchasing another complete assembly.
Every brand will tote their advantages. Spend what you can afford, but a few extra bucks makes the pull much better. It can also make a difference between a white knuckle experience vs a comfortable drive. Hope that helps.
