Scoozah Me, but isn't the condition of the coach itself the deciding factor in justifying the cost of drivetrain repairs? The sales tax on a fifty grand rig ain't cheap. I've not priced crate motors lately, but a crate motor and a reman tranny would really spruce up a nicely maintained coach.
AND it avoids the SMART SYNDROME. Five hundred dollar dealer visits to switch off a check engine light that would not enter into the play with an older unit.
NEW AGE DEFINITION OF "FUN". Play with near bankruptcy to purchase a brand new SMART rig so you can spend 150-hours of a 240 vacation trying to outwit high tech problems that are not resolvable unless you lose five days of work later on playing pinchy-giggle with the dealer, over warranty repairs.
No wonder the public bit the SMART fish hook so hard the tip of the hook is sticking out of their forehead.
