Dedrick,
I have a SB as well and I did several things to haul a pretty large trailer. Most you won't need to do all this... but for SB, you can get a pin box extention, which I have and use a regular 5th hitch

or you can get the automatic sliding hitch that slides the pin back 14" when you turn...

The trailer you are looking at is pretty heavy on the weight, the truck can pull it but you will be over on GCVWR when loaded. So you need to look for a GVW on trailers around 10K when loded or like 7500 empty, and you will be safe
If you are looking at getting a Bumper pull trailer, I can't recomend more, or suggest higher than a very premium hitch I owned once, than the HENSLEY HITCH

They have a free video you can send for that will give you all the info and demo of how it works. It truly makes a TT feel like a 5th wheel when towing.
Other than that, everything else is what you will like to have inside and how much stuff you want to take, will the weight of the trailer take it?... . what you want to use it for, and will you grow out of it in the near future and might want something else? All this has to be considered.
If you do get something pretty heavy, like me... Some of the things you will need to be sure of and do,
suspension upgrade? I did the Roadmaster coil springs sold by Mr. Bob's for the pin weight
Tires? ... I have Michelin XDE-MS 245 70R 19. 5" "F" rated 12 ply rated at 4080# @ 95 psi.
transmission? I had to get a South Bend Clutch for my 6 speed
E-Brake... ... I added a Jacobs E-Brake for increased speed retarding... .
Sooooooo, got some more thinking don't you?
