Hello all. I'm a first time poster here. So be gentle. 😃 I'm currently building a CH Mack for RV use only. Its a fairly long wheelbase single drive with rear Hendrickson Airbag suspension. It has a standard (fully rebuilt) front end 3 leaf parabolic spring set up. I'm chasing a softer front end for RV use but concerned with going outside of safety / engineering standards. I would dearly love to add airbag to the front end and this is very do-able here is Australia. My thoughts in adding air to an already fairly rigid sprung front end won't help me (Happy to be wrong :)) I see all these web based sset ups from the USA especially regarding long wheelbase KW's and Peterbilts and note they have airbags installed with usually 2 shock absorbers, but only run one leaf spring? To me this seems unsafe? One leaf breaks and it all turns to the brown stuff.
Ultimately I'd like to take out one of the 3 parabolic leaves (to soften the ride) and add the airbag to get the correct ride and height. As i'm only ever using this truck for RV use not haulage, i will run a consistent weight on the front end. The RV body will only be approximately 2 Ton so the steer won't be a whole lot different to running around in a commercial environment bobtail (Empty).
Just reaching out for some feedback after telling my brief story. In Australia, we don't have the suppliers and resources you have in the USA so grateful for any ideas or thoughts.
