Getting ready to purchase a set for my '08 E350, both Air Lift and Firestone have good reviews. Which are you using, if any?

The Air Lift LoadLifter 5000
2008 Ford Econoline Air Lift Air Bag Suspension Kit - Videos & 415+ Reviews on Air Lift Air Bags for Towing - Air Lift 1000 & 5000 Install


The Firestone Ride-Rite

I will also be getting the front coil spring helpers, both Air Lift and Firestone make them.

 

I had ride rites on the back of a '79 F250 and we loaded that truck mercilessly while towing a heavy trailer. Ride Rite was the best thing I ever did for that truck. When I get my camper van configured the way I want it I will put Ride Rites on it also.
