Nice RV, you are going to enjoy your camping trips. That is a fairly good-sized TT for a 1500, if the specs I saw were correct, you got about 26-foot of trailer and I'm guessing just a little north of 7K tow weight once the TT is loaded up for camping.
I couldn't find a lot of info on the trailer's braking ability so I'm going to assume it has electric drum brakes on both axels. If you are getting the trailer brand new, you will need to bed the trailer's brakes, something few RV dealers tell people about, me included. Follow the instructions on bedding the trailer's brakes.
You didn't say if you have a factory trailer brake controller but if you do, follow the setup steps in the owners' manual to adjust the trailer brake gain. Once this is done, you will have proportional trailer braking, the more braking effort applied to the tow vehicle will also apply additional braking effort to the trailer. Remember, the trailer's brakes are responsible for stopping the trailer just like your truck's brakes are responsible for stopping the truck.
As far as brakes for your truck I always error on the side of caution. I've used the Power Stops on both my 1500 and 3500. There are other solutions that work equally as well as the Power Stops but I only have first-hand experience with the Power Stops.
