Someone else mentioned it, the 18's have a taller sidewall and you may have more flex there. Are your tv tire pressures at their max?
Also, if the tires are brand new there will be some squirm there too.

Park your truck and trailer on level surface. Then with the truck uncoupled measure fender height front and back. Measure trailer height front and back. Be sure trailer is level as well. Hook up everything and check heights again. Front of truck may be a smidgen higher than the back but not lower. Same with back a smidgen lower but not much.

Boosted, I'll wager that the new 3500 is taller at the hitch than the 2500 and you are towing nose high now. I agree with others that this is a hitch adjustment issue, I had to drop my Equalizer hitch all the way to the very bottom holes when I changed to a 3500HD to keep the TT level. I have 18" wheels also, but with 80 PSI, I don't think sidewall flex is actually an issue. I would pull the entire rig somewhere flat where you can look at it from a distance and see if it is sitting level; I'll bet it isn't. Do some measurements from trailer frame to ground and see what you have.

I have two 2500s 2006 and 2007 I have two trailers and if I try and tow the smaller trailer with the truck I didn't set the hitch up for I can definitely feel the difference.

I find it interesting that people buy really big trucks so they can pull a trailer at 70 MPH.

I bought the smallest F150 I could to pull the 26 foot trailer at 55 MPH and it works just great.

Must be fun watching the gas gauge drop as you drive

I would guess my fuel economy while towing is between 9 and 10 mpg. That is pretty good for dragging around 14,000 pounds through the Rockies and the Sierras. My 2500 is just the right size for my trailers a 32 foot and a 35 foot. T34SP 2006 Been traveling enough to have over 100,000 miles on a toy hauler. Just had to replace the roof May 2016.

The speed limit here is 70 and is 3 lanes, so yes i pull it at 70mph im not one to drive 55 in a 70 and make everyone go around me. The last truck did it fine. I have more to worry about then fuel milage in my life but thanks for the help.
