Lyle,
That is certainly a logical idea. Although, I don't see any reason for going
"coil-over-shock" as that would be a real design exercise. One could simply put
a coil spring in place of the air spring. Even that would be a real design
challenge, fitting the desired spring rate and load into the space available and
keeping the stress reasonable. The problems are probably beyond that, though:
One of the biggest advantages of air springs is the ability to level the coach
when parked on a sloped surface. Another problem is financial: Sure, you can
go to a spring company and they will wind whatever you want - for a price that
will likely be higher than any costs associated with the air suspension. The
weight of a given coach doesn't vary by much, but I'll bet different coaches are
all over the map when you consider all the variations. So the potential market
for a given design will be very small.

Emery,
You bring up a point I have been rolling around in my mind. (Ok, don't laugh
everyone - I'm a newby and am still trying to figure out how all the systems
work) Has anyone ever looked into developing a horizontal coil over shock to
replace the airbags? Granted, the ride wouldn't be the same and it would be a
fixed ride height... However, given the email traffic I've followed on air
compressors rebuilds, leaking bags, lines and valves,?along with plastic cones
that grenade- wouldn't a well engineered coil/shock alternative be worth
developing?
Thanks!
