Headlights are too high towing, getting high beam flashed.

So I had to tow through the night on my last trip, something I try to avoid, but was unavoidable this time. I kept getting flashed by on coming drivers because apparently my lights are too high and blinding people. I have 2016 F250 with the camper package and use an 4 Point Equi-li-zer Hitch. The tongue weight of the trailer is only 700 lbs and the hitch is adjusted correctly according to the owners manual height measurements. The truck rear end drops approx. 1 1/4 from unloaded height, but this is enough to throw the alignment off for the lights. I am looking for suggestions on how to remedy this issue without using the hitch to do it. Using the hitch would put the adjustment out of the normal range according to Equi-li-zer. Basically the truck sags too much even with the hitch attached, or it sags enough to throw off the headlights, however you want to look at it. I have looked into the Torklift spring helpers, and they look reasonable, Is there other possible solutions. PS I do not want air bags, I think that would be over kill.
