@Blaise and
@dreadlocks — I have an honest, good-faith question for you as Rover/Air Suspension users. I’ve seen the refrain we see in this thread — that it’s crap due to air suspension — often repeated about Rovers and other rigs, and yet I see them regularly going on trips that would make Magellan jealous. These criticisms are largely aimed at the complexity of these systems as compared to traditional coils, but complex doesn’t necessarily mean unreliable. Obviously, the system works well enough for the dozens of folks who use it every day, despite having it’s detractors.
What are typical ‘real world’ failures in your experience, and what is the main concern? I have opinions based on lots of reading, countless hours of studying, etc. And I know the prevailing wisdom is coils/leafs over bags — but I have very limited real world experience with air suspension, so I think for everyone’s benefit it would be good to hear from people who run the systems.
I can see two areas of failure with airbags — am I missing any? And what is the impact of these failures in a typical situation?
1) Punctured Airbag — seems like a prepared person could bring a spare, in much the same way non-air rigs will often bring a spare shock? I’ve also seen a lot of airbags inside coil springs, and they are meant to ‘help’ — if they pop, the spring is still there, it just means a bit of poor suspension performance but probably not a trip ending disaster, right?
2) Electrical/Component Failure — this one I guess depends on the system and the failure, but what’s the scope of the problem in a ‘real world’ situation? Stuck in the bush? Drive it out gingerly? Craft a helicopter out of chewing gum, a jaw bone, and a positive attitude to haul the rig out? What’s the solutions to this problem, if it arises?
I work under the assumption that all vehicles — even Landcruisers
— have the potential to fail. The real question is what that failure means — if a failure means a life-and-death, stranded in the back of beyond situation, then that might be a deal breaker. But if a failure can be repaired reasonably easily, or simply means a bit more of a bumpy ride, or a largely optional feature is offline for a bit, that’s less of a concern.
