you've read the other posts. Most folks will tell you to get a larger truck. Once you start towing a load that is over the weight of the tow vehicle, the game starts to get serious. You will have a 5000# tow vehicle and a 7000# trailer load. Really, that's not all that bad. BUT, you have to maintain the trailer brakes. Absolutely, get the weight distributing hitch and an anti-sway for the trailer, so it won't be wagging the truck.
The trailer will probably have electric brakes. That's ok, but they are manually adjusted. That means 2x a season you have to jack up the trailer, crawl under it and manually tighten the star adjuster down on each wheel. Not a big deal, but it is so often forgotten it ain't funny. Once a season you have to take the wheel off, remove the hub and grease the bearings. Again, it's not that big of a deal, but it gets forgotten a lot. Usually, you remember when the hub catches fire after the bearings melt down. If you aren't comfortable doing that, have it done at a tire or alignment place in the SPRING before you tow.
You will need to carry an extra trailer tire (and hub and bearing set if you are smart/paranoid). Make sure the truck and trailer have GOOD tires. For some reason, you only find yourself in panic situations on rain slick roads.
You can also search for how to load the equipment. You want 15% of the load on the hitch. 7000# load is 900# on the hitch. Measure bumper drop without using the weight distribution hitch to determine how much weight you are carrying. (Mfg specs on spring rates should be known.)
As a novice tow-er, buy professional grade chain and ratcheting binders. Expect to spend $200 or a bit more. If you buy good stuff, it's a life time purchase. Junk is seasonal...
