New Truck More Payload
The 5500 Ram CC has those big 13500 rawr. This will get you in the 9800-10200 lb payload range depending on std cab vs crew cab.
I have no idea how much a loaded Host weighs but say it weighs 6000 lb wet. The 5500 truck will have around 4000 lbs for lots of extras.
These number are a estimate and actual payload comes from scaled axle weights.
I see lots of 3500/4500 CC ranch/farm flat beds and a few 5500 CC trucks around stock yards pulling 40' GN stock trailer with 10k-11k lb axles ( tandem dual axles).
Braking with the 5500 pulling a toad shouldn't be a issue. Those big 13500 rawr plus the trucks 7000 fawr = 20500 lbs of braking performance at a minimum.
