Gentlemen,

I've noticed that 5er hitches come in different ratings 15k, 16k, 18k, etc. I need to clear some things in my mind, so please confirm the following.

1
The rating is a maximum capacity rating, correct?

2
The rating has nothing to do with king pin size; all king pins are the same size, correct?

3
It is best practice to buy a hitch rated to, or just abouve your tow vehicle's reserve (after TV's actual loaded weight - trailer) GCVWR (max towing capacity), correct?

Thanks,
Ralph

The hitch rating is based on the GVWR of the trailer you'll be towing. In my case, the trailer's GVWR is 16K and the B&W turnoverball companion 5th wheel hitch is rated for 18K.

All kingpins are the same size. In fact, you could tow your 5th wheel with a Class 8 (over the road) tractor - 18 wheelers use the same kingpin size as our 5th wheels.

Does this help?

Rusty

Unless you forsee upgrading, why would you buy a heavier rated hitch? It would be like spending $$$ that yu don't have to. The correct rated hitch will do the job.

Yes Rusty that helps.

charliez, Rusty may be like me in that I know even engineers make calculation errors (example, some elevated bridge in some hotel a few yrears back). I would rather be slightly overated as a precaution. Every body looks at things differently. Thank you for your input.

Ralph

In my case, the B&W companion 5th wheel RV hitch only comes in an 18K rating, which is adequate for my requirements. I wanted this hitch because of the flexibility to tow gooseneck trailers as well as 5th wheel trailers while retaining a clean bed floor when neither hitch is in use.
