I have a class III hitch on my truck. I am looking at a trailer that is rated as a class IV can I use it?
I just need to know if I can interchange and use the class III trailer hitch on a trailer that is rated as a class IV even if I am not fully loading it and it is within a class III rating. Also will a Class III accept a ball size of 2.5/16"?
A class III hitch is rated at 5,000 lbs total weight, with a 500 lb tounge weight. As long as you stay within these limits, you should be good to go.
