Nice upgrades to your Ram 1500 to make it tow better, but do keep in mind that it may not help you from the what is "legal" towing perspective.
Most of those Rams 1500 have the lowest payloads of all 1/2 tons trucks with some being in the neighborhood of only 1000 to 1200 lbs or less payload (most of the competition is in the 1800 lb to 2100 lb payload range or more with their half tons).
So generally speaking anything above one 150 lb driver placed in the truck has to be subtracted from both the payload capacity and the tow capacity at a rate of 100% of whatever those weights are. Fat drivers over 150 lbs, spouse, kids, dogs, tools, Quads, camp gear, etc. All those extra have to be subtracted at 100% from both the payload and tow capacity of the truck if placed in the truck.
Your only hope with staying legal with that rig is putting absolutely nothing in that truck besides yourself and then placing all cargo (no people of course) on the trailer balanced as best you can. At least this way your towing capacity is the highest it can be and only 10% of the trailer weight ends up as payload on the truck (assuming you balance it well) which is still gonna max out the puny Ram's payload capacity.
I am not saying the truck will not handle it with your upgrades, but if you ever in an accident (whether your fault or not) you better well be "legal" or you may find out you have zero insurance. Having no insurance may not be much of a problem if you own nothing and live paycheck to paycheck anyhow, but if you have assets then you will soon join the former category when the insurance companies look for any reason they can not to pay.
