Has anyone ever tried to leave the air ride on the cab and connect it to the box with a flexable gasket? I am working with a large gasket company to develop something that gives a water tight seal, moves freely with the cab, and does not squeek or make noises. This will enable me to have a better ride than the other conversion shops are producing. Does this sound possible?

Is the air ride in the truck portion typically removed on conversions? So you remove it and then end up with a truck that has a harder ride?

Why can't it be left on the truck?

Does the conversion cabin portion ever have air ride?

Have you ever looked at the way a passenger train sections join together? There is a door on each end and the trains join by an 8" wide rubber boot. It doesn't keep everything out, the door is the next barrier, but it must help.

the cab is not air ride but the seats are.

Pretty sure all Showhaulers have the air ride attached still. At leas there are shock absorbers there, its definately not a solid mount.

The Haulmark site brags that they leave the cab shocks on, while their competition removes them and replaces them with solid bars.

My 2001 Showhauler has a chunk of wood - no air, no shocks.

Sort of true: There is actually a boot on EACH car. They "meet" and contact each other with metal face plates which are the wear surfaces between them, and there is a lot of sliding between them. You really can't compare this to the boot between the cab and coach, which would only be one piece. There would have to be quite a bit of "slack" in the boot to handle the movement between the cab and coach that an air-ride cab would give. Does this help you?

Yep, ours definately has air ride or shock absorbers. you can feel it move seperatley from the box when you drive, and you can see it when you look underneath the cab.
