If I’m understanding your question correctly, just need to crank the landing gear a turn or two. I had this problem when I first started hauling Intermodal. I was 13.8 with the container and I had to crank a few up higher just to be able to get underneath and hookup. Also had to buy 22.5 insteady of the 24.5 I always ran. Low pro 5th wheel can help too. Can actually pick one up at a semi truck junk yard for pretty cheap.
