I have read some threads on here regarding air suspension however i have been getting very mixed answers from dealers / fitters etc. I was told by one dealer/fitter that i wouldnt benefit from air suspension on a van of my size.Another supple/fitter has told me i would benifit alot from having a system fitted .Very confused regarding the issue and obviously dont want to waste my money if its the case i wouldnt benefit.I know its an expensive item but i plan on keeping the van for a number of years and why not make life a little easier and more comfortable.Has ayone else with a similar sized van had the experience? Sundance 590 approx 6-5m.
