My Roush came with 2.0 Fox racing 2" suspension kit. Rides great, no issues however I recently bought ba oat and there's a bit of sagging when towing my boat. It's a 22' pontoon and I want to say it's 4200 lbs but I'd have to look at the paperwork. I'm new to trailering anything and I'm wondering if I will create any issues with the sagging.

Should I look to air bag the rear or new leaf springs? My understanding is the Fox setup can be tuned/adjustment, maybe I can stiffen the shocks?

Thanks for y'alls help.
