What Would Cause 2016 Tiffin Allegro Open Road 34TGA To Lean
Updated 10/29/2026 | Published 10/24/2026
Question:
I have a 2016 Tiffin Allegro Open Road 34TGA on a Ford F-53 chassis that has a very noticeable lean toward the front passenger side when sitting on level ground with the leveling jacks retracted. I measured the frame height at 27” LF and 25.5” RF, and the axle-to-frame measurements are 12.25” LF and 11” RF. The rear is nearly level at 26.75” LR and 27” RR, so the issue appears to be concentrated at the right front. I have installed SumoSprings on both the front and rear, but they made very little improvement to the lean. I am now considering adding front air bags so I can compensate for the passenger-side difference. Would front air bags be an appropriate solution for this, or would you recommend addressing the factory leaf spring or another suspension component first?

This to me sounds like a problem with the factory suspension. I would inspect the springs and replace as necessary as it does sound like the one side of the RV has more worn out suspension than the other side. Does the RV have more slide outs on the side that leans down? If the suspension is all in solid working order then an air bag kit like the part # AL88240 would be the correct call. How many miles are on the suspension?

The sumosprings won’t repair the problem. I’m with the above comment it is a problem with your factory spring system. I do recommend the air bags (4) of them. It makes the ride so much smoother and you have more control when you encounter wind natural or from traffic. Good luck Rick

I have them, and they would work great for you. I had to do a little custom work because of the radius rods I have installed. I sag in the back, so I have front and rear pressure controls. You set up side to side just as easily. I would never go back to Summos. They lifted my rear 2" and it has been awesome.
