Regardless of what Ford may want to define as a "tune", the important part in this comparison is how fast the motorhome can accelerate or climb hills/mountains. And that primarily comes down to power-to-weight ratio.
305 HP to a 12,500 pound Axis/Vegas is equal to
362 HP to a 14,800 pound motorhome.
While it's true that Axis/Vegas have 2-valve engines with less power than larger motorhomes based on F53 Ford chassis which have 3-valve engines, the average Axis/Vegas should still accelerate and climb significantly faster than most other Class As which so often weigh a lot more than 15,000 pounds.
Even if we include the weight of a toad the Axis/Vegas should hold its own against larger and heavier motorhomes based on F53 chassis.
