Look on the hitch, next to the receiver tube. There should be a sticker on there that will give you the info you're looking for.

24 hours in a day, 24 beers in a case. Coincidence? I think not.
300# tongue weight rating on mine as well, but I didn't trust it so did a lot more welding.

The hitch on my HT is also rated for 300/3000. I towed with it last weekend but don't trust the minimal support it has so I'll be adding gussets and support before our next trip
