New Super C Motorhomes from Thor Motorcoach

I wonder what percentage of buyers actually keep a class C for enough miles for the (hoped-for) extra durability of a diesel engine to matter? Seems like the tales of the house going to pieces due to leaks are far, far more common than worn-out gas engines. I understand the desire for one if it's a matter of moving extra weight, but I honestly can't recall but maybe one thread on replacing a gas engine in a C.
