You may need a shank for the Weight Distribution hitch that is an inch or so longer than your existing one, to gain some tailgate clearance.
Some people will disassemble the head from the tube on a tongue jack and drill new holes and remount the head sideways (the triangle base only fits one way).
I have a Lippert jack that was on the trailer when I bought it in 2019 and it has worked well since then, and I've used it a fair amount.
Probably the BEST tongue jack are those made by
