For what it's worth:
Torque to the drive wheels is what matters - not engine crankshaft torque. Horsepower gets converted into drive wheel torque via gears. High engine horsepower gets converted into high drive wheel torque this way. The big Chevy V8 or big Ford V10 in their respective cutaway van chassis used for motorhomes can be geared to put way more torgue on the ground at any given vehicle speed and weight than a 186HP motor can at that same given vehicle speed and weight - regardless of the 186HP engine's crankshaft torque.
That being given, 186HP can sometimes be gotten away with in small motorhomes under certain conditions, with the result being better average fuel mileage
