In your other thread you said, “At certain speeds, and only when the truck (in signature) is heavy with either people, cargo, or the TT (tongue weight per Jayco is 470 dry), the truck has an 'almost-too-low-and-too-deep-to hear' rumble that lasts until the truck gets either above or below the 'problem' speed....it happens at around 10mph and again at around 35 mph..”
So it seems to me the dealer really isn’t at fault for testing with a load in the bed since that was one of the things you said caused the vibration.

Quote:To try to duplicate, the dealership service rep put some amount of weight in the bed...he didn't sense any issue...tried to tell me, 'there's nothing wrong'....I didn't accept that
Once he hooked up to a trailer similar in weight to ours, the problem surfaced....now they've replaced the driveshaft
The point: it's important that, if a problem only occurs under certain conditions, that we insist the repair tech duplicate those conditions in testing
Good point and glad the dealer agreed to hook up another trailer to duplicate your trucks drive line shudder. Not many dealers will do that.
Just weight alone in the trucks bed may not cause a shudder issue....but add several thousand pound trailer plus weight in the bed created your trucks shudder.....especially under hard acceleration getting the combo moving.
