I recently installed the SuperSteer trim unit Model Monaco SS200R/M on my 1998 SMC Beaver Patriot Savannah with a Magnum 8 air bag B Chassis.
To be fair I have never had a Safe-T-Plus before so I have no idea how they handle without the trim unit. With the exception of getting out the 2 - 6 inch 3/4 inch bolts the installation was very straight forward.
The trim unit will not make your MH handle like a sports car, but for me handling was improved. It is easy to set the trim unit with a simple flip of the momentary switch. If it pulls you can correct it. If there is a side wind you can adjust for that. Once you have it set correctly driving is easier than it was before I installed it.
While this was designed to fit Monaco era Beavers it also fits my SMC Beaver. Before I ordered it I spoke with John at Henderson's and sent him several photos. The frames appear to be identical and I had plenty of room to mount the trim unit between the frame and fuel tank. John also answered all questions that I had about installing the unit. He was probably thinking how do I get rid of this idiot, but he answered my questions non the less.
You will have to verify if it will fit your coach or not, but I suspect a lot of us can benefit from this system. Its not cheap. Mine was right at $1200.00 with the safe-t-plus including shipping and taxes.
