Hi being a newbe hear aand in rv'ing I see a lot of post's concerning towing with a half ton p/up I have a 2014 Ram 1500 with a 10/k hitch and with a 14150/bs GCVW my trailer is a 2007 forest river...
As stated, payload is often exceeded before tow capacity. Of course the dealer said you could tow that much weight. What you need to figure out is if the weight you are carrying exceeds the GCWR of the truck. That is if you REALLY want to know...
