New steer axle??? Overweight on steers empty.

[DT_Duh_Trucker]

I'm heavy on my steers!!!! With empty trailer and tanks at 3/4 I was at 12,380lbs. My axle rating is 12,350. Now I know I get an allowance of 400 hundred or so depending on the state for my apu, but is there anything else I can do to help move the weight back? Should I Slide tanks back a little in the straps? they are not under the doors like some prostars they're under the sleeper pretty much. Replace the axle for a higher rated one (this is the option i see being best for peace of mind at weigh stations)‽ My truck is 274 wheelbase. I have my 5th wheel back a few notches before the rear or one or two notches from being centered between the drives, but being a longer truck it makes it tougher to maneuver through places like DC, NY etc when I do go so i want to try to avoid going back any further IF possible. Any suggestions or help is appreciated. Also, I pull flatbed so yes I have a headache rack and chains/binders in there. Going home next week and if there is something I can do or have done I'd like to try to do it while I'm home for a week. Thanks for your help. Picture of truck is attached.....if I did it right lol.
