Question:

Took my Reese RP66153 SC Weight Distribution System off my old travel trailer which I purchased from etrailer in June 2014 trying to remount on my newer trailer and I cant find install directions. This trailer has an inverted coupler and it seems there was a differance on that and other measurements, TW 794# and GTW 7985# any input where I can find directions. Thanks

@Ja this system was discontinued and that pad hanger cover is no longer available as a replacement part. I would reach out to Reese directly and see if they happen to have any available.
