Go to camping world and buy the prodigy, they should also have the correct pigtail adaptor to connect to your titan. It should be plug and play.
If you have an O'rileys Auto Parts close by they have a brand of brake controllers by a company called Hayes, they sell a brake controller called a Genesis...it's very similar to the Prodigy. O'rileys should also have the pigtail adaptor you need.
There is a cheaper proportional controller called the Energize III...it's pretty good and the controls are easy to use.
I would steer you away from the time based controller but they are 10000 times safer than no trailer brakes.
Do not tow this trailer without brakes. It's just not worth it.
As far as WD is concerned many on here will help you spend 500-600 on a hitch. The standard WD hitch by Eaz-Lift or Pro Series are fine and you can be safely towing for about three hundred bucks.
Remember for trailers over 24 ish ft you need two friction sway control bars.
Thanks and good luck!
