It's only a #7500 GVWR trailer for Pete's sake guys....
Will your truck be maxed out on it's ratings? Yes..
Will it implode the moment you go a few pounds over the trucks payload? No..
The stock tires will have more capacity than the rear axles GVWR, so you will want to pay attention to that more than anything.
If they are still the OEM ones, you might consider some new ones anyway, but look for some LT rated tires if they are 18" ones. If they are the 20" ones, you can get some XL rated tires that do really well IMO. (I know, I've got a set and they are great!)
The 5.0 will need to rev, but it'll have plenty of punch when called on.
If you don't pack the trailer to the gills and don't load a cord of wood in the bed, you should be fine. Yes, you might be a tad over the payload, but that's a call only you can make.. If it bothers you, then you need a truck with more payload.. If not, and don't go overboard, you will be fine.
Good luck!
