Noob,
The website Kwire provided also has a page with links to the manufacturers tow ratings. Those ratings are your most accurate guide for deciding what tow vehicle you need once you have the weight of the trailer.
My 36FL has a max gross weight of 16000 pounds and that is the weight I used for choosing my 2 wheel drive Ram 3500 DRW. With the 4.10 axle and automatic transmission it has a payload capacity of 4114lbs and tow rating of 17,950lbs.
