Old-Biscuit has it right. You will most likely be over your rear tires carrying capacity.
A 16K 5er and yours will easily get there will have a minimum 20% 3,200# pin and easily up to 25% 4,000#.
So now you have a choice of blindly towing it like most will do or installing a set of much higher load range "E" tires from a new RAM or 19.5 tires and wheels or better yet get a truck that the new RV is within it's ratings.
Of course all JMHO!

Your going to be over on your RAWR IMO. Start shopping for tires with a higher ratings. 19.5 will get you within your trailers pin weight.
