I am going to recommend the 600 Trunnion Fastway e2 Weight Distribution # FA92-00-0600 over the 450 Trunnion # FA92-00-0450 and 600 Round Bar # FA94-00-0600 for your 2015 Forest River RPOD 179.
The 600 Trunnion Fastway e2 Weight Distribution # FA92-00-0600 is rated for tongue weights of 250lbs to 600lbs and a maximum trailer weight of 6,000lbs. With this hitch if you decide that you want a little bigger trailer you will be able to use your same hitch.
