Cyclone 3800 tow truck

Pardon the newbie question.

I'm impressed by the Cyclone 3800 and will likely be purchasing a used one in 2017. Would a Ram 4500 be sufficient to tow the RV.

I want to be over trucked so that I don't have tow capacity issues in the future.

The 4500 has a tow ability of roughly 19k lbs., but I'm a little confused about the Cyclone's two displayed weights (dry and gross). What is used to determine tow parameters?

thanks much
