We are looking closely at the Jayco 28.5 RSTS and have some concerns about the weights. We will be towing with our 2016 Ram 2500 4x4 crew cab with the 6.4 Hemi and 3.73. Max tow for the truck is 126...
You would have no problem towing/carrying the Jayco FW. However, I would not be happy with the 1,590 CCC. This tells me that the trailer suspension is too light duty, likely only 4,400 lbs axles. These axles will also have smaller brake drums/shoes. If it had the 5,200 lb axle upgrade option, you'd have way more CCC, with larger/better brakes.
