    On our first long European tour in the new van. As I'm well within my load capacities for the rear axle the van is noticeably lower. When I return back to the UK I intend to have the rear fitted with air bags to help the suspension. It is many years since I had these fitted on a motor home and units change. Can anyone recommend a pair of quality units for DIY ibstall

    This is something I will be doing in a couple of weeks, I'll be interested to see what kit is recommended.

    We had ours fitted by AS AirSuspension - both in this van and our previous one - excellent system and excellent work by Phil Berry at AS!

    Airbag assisted rear suspension... very, very highly recommended.

    No, there is a "Tee" joint underneath. This guy makes them in Poland I'm sure he'd sell and extra gauge for little money.

    You can ask on 07921128933, his wife runs the business in UK from St Helens, I collected from there, really nice helpful person.

    In theory I prefer the T as if there is a failure both sides go down.

    Mine were done individually as standard.. In fact the control panels as bought from AS have two buttons on .. one for each side

    Note.. While control panel and wee on board 12v compressor is nice to have, I used the simpler option of tucking the ends in the gas locker and using an air line for the first year we had them.. It was only after I decided to get all posh I bought the control panel and a 12v tyre compressor from halfrauds and fitted that..

    I fitted drive rite myself years ago on a few vans..bought it from Dublin head office as cheaper (No surprises there!:censored:)

    just run separate air lines.....I always went for cheap basic kit as bags small and can be pumped up with a foot pump and checked with a tyre gauge

    The two sides tee'd togother is a bad idea, it wil encourage the thing to roll over on corners, as I discovered. As the weight starts to shift it forces the air out of the "loaded" side & into the "unloaded" side which exagerates the body roll. I would go as far as to say it's dangerous.
    My system has one inflation point & guage, plus a pair of valves to select which side to inflate/deflate.
    I made the mistake of leaving the valves open once, Never again!

    I hadn't thought of that. Easily solved with a restrictor in one line.

    Dunlop don't recommend a 'T' off system, each air bellows should have their own air line back to the air gauge/s this way you can adjust the air pressure to each bellows to compensate for weight distribution and road unevenness..

    I fitted a Dunlop system from Marcle and really easy job. Had the one with single pump up valve with gauge and two switches. Open both n/s and o/s switch, pump up on level ground then knock both switches off, both air bags same pressure both sides.
    Opposing air bags (as in n/s & o/s) should NEVER be pneumatically joined. Not only can it seriously effect on the roll (side to side), it can cause SERIOUS body weave once it gets going.
    :eek:
    Brian, get it separated - please.(y)

    Hope it helps.

    I was worried that my insurance would consider this a modification, so phoned them beforehand. They said that provided it was fitted by a recognised trades-person, there would be no excess. I asked if Watling Engineering would qualify and they said Ok!
    I was recently weighed and told that because I had air suspension the 30kg overweight on my rear axle would not be a problem if I fitted tyres with a wider profile.
