Need help with a hitch

[NotFastEnuff]

Hi everyone. First, I want to say that I'm loving this site! You all are very helpful and supportive!

I have an 86 C10 fleetside short bed, and I need a hitch. I need to pull a single car trailer to move some other projects around. I've got a step bumper, but I'm afraid to use it. There's nothing "wrong" with it, but the idea of pulling a trailer with it makes me nervous. I plan to switch to a sport bumper as soon as I find one, and I'd like to do a hidden hitch, but I don't know how I can pull that off with the step bumper.

Also, in searching for hitch info, I keep finding sites that say a hitch will fit from 67-00 Chevys. I'm pretty sure that's bunk. Can you guys please tell me all trucks that we can use hitches from?

Thanks everyone!
