Another user of Mobil 1 oils (30+ years). While the 5w-20 is probably fine in most applications, a MH sees a lot higher loading than most PU's, SUV's and cars. I suspect that Ford wanted a "standard" oil across their "standard" engines.
However, it is interesting to note that that Ford does recommend a 5w-50 oil in some of their supercharged Mustang engines.
I've used 15w-50 in mine without issues, but have now standardized all my vehicles and engines (15+) on their 5w-40 oil. It may cost me a 0.1 or 0.2 mpg, but I feel a lot better with my foot on the floor pulling my toad up a long grade.
