I agree that some mods should be standard equipmen. The steering stabilizer is a safety item. It impacts wandering in wind or bad roads or just the turbulence by a passing truck. It prevents accidents caused by road debris. It should be as much standard equipment as seat belts. The centramatics are a preference. The wheel alignment is maintenance. I do this to my cars. The rear sway bar is something I tossed into my bargaining for the purchase. I am not sure I would have done it otherwise. I like the fact Tiffin is making some suspension improvements an option like sumo springs. I have done many other mods with new motorhomes in the past. This one rides and handles besotted with no changes so these changes are enhancements where they were a necessity in the others.
