1988 Ford E350 Air Suspension.

Sorry for the confusion, i was suggesting to do a spring leaf in place of the bags.
When i added a leaf to the pack it was under $500. Adding bags was close to the same at the time.

My latest attempt to give me more ground clearance didn’t work using a wireless compressor airbag system for $1700. Ended up getting a full refund parts and labor. That system developed multiple leaks in the bags, fittings and compressor over the first few days of installment.

While it is 35 years old, it only has 40,000 miles on it. Runs like a champ and looks pretty darn good. But I hear you.

^But only as a bolt on add a leaf. Not really worth rebuilding spring packs unless there’s actually broken springs.
Camper is over 30 years old. Name of the game there is not spending a lot of money compared to the value of the vehicle.

If the rv rear sags below level then bags will bring it up to level. If the rv already sits level the air bags will do very little to raise it above level.
Therefore it will depend if they are going to help become level on a site.

If need be, add a leaf to the spring pack instead. Steel doesn’t leak air.

Thank you

Pretty basic simple effective all purpose upgrade.
I’d think hard about shocks too while you’re in there unless you know yours are good.
