I have a 2010 Pilot that I used frequently for work and play towing a 4000-lb trailer along with a 500 lbs of gear in the truck. My trailer has a some tongue weight which creates some sag on the truck. Does anyone have any suggestions on an aftermarket air suspension solution to help stabilize my rear? Would love to hear how any of you handled this? let me know.... any advice is great advice....THanks!!
