It isn't about these land barges---its about taking something that is grossly under what weight carrying/towing /braking ability that he needs and then completely re-engineering it still another level of power/fuel economy that will still be inadaquate----

about all on that vehicle that is up to the task are the headlights and wiper blades--maybe the steering column----

the change to a heavier engine will require heavier front end components---brakes, rotors, springs/shocks, tires and wheels

the change to the rear the same plus a different housing, wheels/tires---

and after all that , it won't have a frame strong enough to pull his trailer, plus the balance front to back would be a night mare
