He asked if I would like to have the SMI One coach portion of the SMI system for my Newmar Mountain Aire. Even though both coaches have diesel engines and air suspension systems, I am not sure if the coach part of his AF One system, which is new and has never been installed, would work on just any motorhome chassis. The coach I now have is a Newmar with a Freightliner chassis and my previous coach was a Blue Bird Wanderlodge on a Blue Bird chassis. I will call SMI to see what they say but my guess is the coach part of the SMI brake system will not be compatible with another chassis brand.
The system is generic to any chassis and any toad. The only incompatibility you might see might be caused by the RV portion being of their old style and the toad being obviously their new. About 3-5 (?) years ago they did change how they did things and there was a change in the hardware. Regardless, SMI is the place to check with. I talked to them a few months back and they assured me they had a full supply of spares for the old setup, and of course, for the new. If you do have two different generations, you might be able to get them to sell you the parts to complete either setup. Obviously, the cheaper of the two.
I wouldn't hesitate to use either the old or the new. Both systems are nothing less than outstanding. We've probably got about 98,000 tow miles on our older model, and the only failure we experienced was when the air actuating cylinder cable on the toad failed at the firewall clamp. The edge of the clamp was sharp and cut the cable. As I recall, I sent the cylinder back to SMI and they replaced the cable and returned it in less than 2 weeks. Less than $35, including postage. It doesn't get better than that.
PS: on rereading your post I realized I got it backwards. The coach has the new and the toad may have the old system. Comments still apply---sorry I got it backwards. Old age or something (LOL)
