I'm not privy to Keystone's decision making but the added insulation and split systems would be added weight. Load capacities are a sales point (look at pick up truck trends) A reduction in load reserve would require higher capacity axles, rims, tires, etc. resulting in higher cost, lower sales. RV's are a compromise in every respect but Keystone, like every manufacturer irregards of the product, have one goal and that's increasing sales. The climate in Wall Street has been placing greater pressure on increased sales for the last 30 years or so as investors are in for short term gains.
