You need more information to know if you need this or not. Depends on the weight of the trailer loaded along with what the tongue weight is. Once you know the tongue weight, you'll know what you need to do. You want to be in that 10% tongue weight compared to the total weight of the loaded trailer - then you don't need any of these other things, unless you're trying to tow a trailer with a half ton pickup - which I cannot recommend. I see a lot of people trying to tow heavy things with a 1/2 ton truck - but it'll always be a loser compared to a 3/4 or 1 ton truck - you won't be happy.

Etrailer.com has a tongue weight scale that you can purchase - it'll tell you what your tongue weight is - and then you just go to a scale and measure the entire trailer on the scale by itself - so you cannot be hooked up to do this. Pain to do, but it is the safest way to really know what the deal is. Or you can weigh the whole setup, then go back and weigh just your truck and subtract - that works too.

Best of luck!!!!!
