there are reasons there are no 40++ diesel pusher style motorhomes with gas engines if it takes a 9 litre 425 HP motor with 1250 lbs torque to move my 36000 DPMH efficiently how would a gas engine ever do that (realistically)
When I was a kid on the farm we had a GMC tandem axle gas powered truck tractor. It had the TwinSix V12 engine, it was a 702 cu. in. that made a whopping 275hp and 630 ft./lb. of torque....... at 1,600 RPM.
Yes, it made its best torque at 1,600 RPM.
It would haul 60k to 80k of potatoes or grain just as well as our diesel powered REO would.
It’s not a matter of what CAN be done, it’s the ‘coffe shop factor’, the guys that buy $80k pickups with big diesel engines as ‘daily drivers’ because they look so good parked out front of the coffee shop on Saturday night.
The same goes with $500k motorhomes, the average someone spending that much doesn’t care about efficiency, economy or durability, it’s bragging rights.
You got it, spend it, no problem.
A buddy of mine just spent $120k on a Tesla X, claims it’s so great because it costs him soooo much less to drive to his weekend place.
Ok, so he ‘saves’ $60 a week for 6 months of the year after spending $120k on a new car.
