Hi new to this site and would like some advice. We have a 2002 Swift Sundance 630g on a Fiat Ducato 2.8jtd. We would like to fit rear air suspension, is it worth doing, if so which is the best one to fit

I recommend the kit from marcle leisure for under £500. will take any mechanic an hour to fit. makes a huge difference to the drivability of a motorhomeHi new to this site and would like some advice.

In my humble opinion yes
Why well a few reasons I prefer it
Better handling into corners
The ride height can be lifted by increasing pressure giving more ground clearance at rear this will give better load transfer from rear to front so keeping axel loadings more balanced and in soft ground blowing it up to max pressure put more weight on front axel giving far more traction
When running fully loaded its a far better ride no rear axel hitting bump stops
When loaded to max Headlights will not be shinning up so it looks like you are on full beam
This one is purely my opinion if air suspension is set to correct pressure when loaded it puts less stress on side walls of rear tyres
As for setting pressures to start with it's all trail and error till you find the right set up for you
We now run at
30 psi light load (weekending)
40 to 50 psi med load a(a week away)
50 to 60 max load (2 /3 weeks away)
80 psi when running over loaded (3 months in morocco Elaine's shoes and wine enough food for a army full water tanks and my booze )
It totally changed our van and I consider it money well spent £450 or there a outs
Plus when running grossly overloaded like most of us do at some time it levels van out so local plod and VOSA can tell at a glance
But don't listen to me I talk bull and no one listens anyway
Do it

Are there any recommended pressures for air suspension. I put about 20 psi in mine but that's not based on anything scientific other than the Van tends to crash down over potholes, level crossings etc at anything higher. I have read that air suspension is an advantage on older MH's where the suspension springs and shockers are getting a bit tired therefore acting as an assist to them.

Sorry to disagree but there are a couple of glaring errors in your statements:
" The ride height can be lifted by increasing pressure giving more ground clearance at rear this will give better load transfer from rear to front so keeping axel loadings more balanced and in soft ground blowing it up to max pressure put more weight on front axel giving far more traction"
Increasing the rear ride height will not affect load transfer and will not improve front traction at all!
"This one is purely my opinion if air suspension is set to correct pressure when loaded it puts less stress on side walls of rear tyres"
The load on the tyre sidewalls is purely the mass of the vehicle resting on those tyres, altering ride height or changing suspension systems does not alter the mass of the vehicle so the load on the tyres sidewalls is exactly the same. Air suspension can reduce impact loadings slightly though, such as when driving over potholes by allowing more compliance in axle movement.

Air springs used for rear suspension applications are designed to enhance the handling performance and stability of your vehicle by supplementing your vehicle's existing suspension system.
Benefits:
Levels vehicle when you are hauling heavy loads
Increases front wheel traction, improving steering and vehicle balance
Levels headlights, thereby increasing visibility
Enhances braking and handling, even in adverse road conditions
Can be adjusted to accommodate varying loads
Reduces rear-tire wear
Reduces stress resulting from extra weight on vehicle's rear suspension
Reduces rear vehicle sag
Provides an additional contact point for suspension system, distributing the load evenly
Provides additional vehicle stability
Enhances the ride of the vehicle
Prevents bottoming out
Adjustable springs can be individually inflated to balance out and redistribute uneven vehicle loads
