As far as I can tell, we have no basis for saying the rear end is sagging "badly" and have no way of knowing how heavy the tongue weight is. The OP simply says the rear is lower than the front. Even with a properly sized and adjusted WDH, the rear should drop more than the front.
To provide meaningful advice, we need to know:
With the trailer attached and no WD applied, how much does the front rise and how much does the rear drop relative to the unhitched heights?
With the trailer attached and with WD applied, how much does the front rise or drop and how much does the rear drop relative to the unhitched heights?
It is not unusual for the rear to "squat" 1-2" more than the front when the WD is properly adjusted.
Well, I came across and found the interesting topic actually and I have done lots of research over there and found that there is ord F-150 air suspension kits work along with your existing springs and are completely adjustable. You can stiffen up your F150 air suspension when you're loaded down with your pal's bedroom set or towing your water ski boat up to the lake. But, later when you're just driving across town you can readjust your Ford F-150 air suspension for a softer ride. A Ford F-150 air suspension kit keeps your truck level throughout an infinite variety of loads.
