Hitch with new truck

We trade in my old passenger car and trade up to a Ram 3500. Now with
that we have much higher truck. Not being a hitch expert by any means.

Old: 2011 Ford expedition, base of hitch receiver 17"

New: 2014 Ram 3500, base of hitch receiver 22"

Current hitch has a small drop for ball to trailer. What the best way to
determine the drop we need?

TT: Dutchmen 2014 261BHS
TV: Ram 3500 6.4 HEMI, 3.73 6ft bed 2014.

Level the trailer and park the truck in front and measure the needed drop distance.

Go on Equal-i-zers web site and follow their instructions. They have several shanks with different drops to fit any requirement. Most manufacturers have the same.

When I switched from a 150 to a 350 the receiver height difference was about 6 inches. I could lower the ball about 5.5 inches with my existing shaft. I put it as low as it would go and hooked everything up. It is not nose down, it is level or slightly nose up but it tows great so I have gone with in.

Your goal is a perfectly level floor of the trailer, front to rear, after you have the trailer wet and loaded and the spring bars of your weight-distributing hitch adjusted tight. Jamie65 is on the right track, but it's a bit more complicated than that, because the hitch weight lowers the rear end of the tow vehicle.

1] Use a 4' carpenter's level and get the floor of the trailer level, front to rear.

2] Get the GVWR of the trailer off the sticker on the front of the trailer. Multiply that GVWR by 0.125 (12.5%) to get the estimated hitch weight of the wet and loaded trailer.

3] Back the pickup up close to the coupler. Lower the tailgate and have people (adults, teens, kids) with total weight of about the estimated hitch weight sit on the tailgate. Then use Jamie65's procedures to determine the amount of drop your shank/ball mount will need.

Don't even think about towing that big TT without a high-end weight-distributing hitch, such as a Reese Strait-Line, Husky Centerline, or Equalizer. Those hitches all have an adjustable shank that should have plenty of drop for your needs. But just in case you need more drop to wind up with a level trailer, they all sell adjustable shanks with more drop. For example, here is one with up to 8-5/8" drop:
Weight Dist Shank - Drop Only - 11" Long - up to 8-5/8" Drop - up to 1,400 lb tongue weight
Grumpy ole man with over 50 years towing experience. Now my heaviest trailer is a 7,000-pound enclosed cargo trailer, RV is a 5,600 pound Skyline Nomad Joey 196S, and my tow vehicle is a 2012 F-150 EcoBoost SuperCrew.
