Looking to find out if anyone with same layout has air bags installed. 2nd owner of a Ford E450 model 2300. RV had approx. 7000 miles when purchased. Noticed on shakedown local trip for couple nights that there was a lean. Confirmed during 9000 mile trip that right side rear is approx. 1.5" lower than left rear .It usually takes a 2x10 under right rear duals to level at campsites. Does not matter if loaded or unloaded except with full fuel tank it seems to drag more on parking lot entrances. On my layout the dual batteries, kitchen plus appliances, LP tank, queen bed and fresh water tank are located on right. I replaced Dinette with 2 Lambright Recliners (lighter load). No slides and only heavy items on drivers side is Generator and holding tanks that are never more than 1/2 full. Would have figured lean out before trip but with slope on driveway it sits perfectly level
I have not weighed to confirm right side is heavier and springs look good to my untrained eye. I researched this forum and looks like Forest River started installing the Firestone system on newer RV's. Would like to hear opinions before I spend money at shop or tackle install myself.
