We took the Sierra/Sandpiper tour & they knock them out in about 3 days.
However once you place your ordered for a unit itís about 3-4 months until you are picking it up from the dealer.
I think if they slowed the lines down by maybe 2 units a day they could improve the final product quality & have far fewer warranty issues.
Those guys/girls are moving at brake neck speed. Itís easy to see how things are missed.
