I never had any need for air bags until I got my cargo trailer for the motorcycle. The extra tongue weight of the single axle trailer would drop the rear end about 2”. I added the Air Lift 5K air bags and it resolved that issue.
With just 50# the hitch height returns to 16” with the tongue dead level. To my surprise when not towing I put 20# in and the great ride I always enjoyed got even better... go figure? Don’t have a built in compressor but both air lines run to a single Schrader valve and my portable compressor tops them up nicely.
:C
