Shortbus type motorhome (built on the 3/4 ton van chassis) or the massive M400/M500 Chassis land battleships (the 40-60’ monsters)?
I’ve driven an M400 Chassis battleship motorhome with a 440 and I can say this... you could take 3 spark plugs out of the 225 Duster and it would still beat the motorhome. Yes the 440 gets up to speed, but granny on her mobile scooter is going to hit 60mph minutes before you do.
