My hitch setup also starts with setting the hitch ball 1” higher than the trailer coupler.
If you need to adjust height outside the current WDH, you can get a replacement longer drop/rise drawbar or shank, sometimes called a stinger.
As recommended earlier, you need to test fit it on the new tow vehicle. I was lucky. Swapping from a 2008 Explorer to an F150 resulting in my TT going from level to 1/2” high front, acceptable to me.
After flipping the TT axle, I had to literally flip the WDH on the shank. No problem except having to find/borrow the large wrenches & sockets, a 5” rise.
