Will you try for the inventory models? I saw you got in the queue for a new 5.0, great!! I do see that the original date they give you gets shortened a lot. You may well have it before the 2023 camping season begins.
Ours is a 21C, we ordered it last Spring (Iím not sure which month). Started out with a date way out in Oct 2023. It has moved up so many times and is now Feb 2022. But you are right, 5.0 has a longer lead time because they only have the equipment to make one at a time. But yes the very long lead time they give you is a pessimistic estimate and it gets a lot shorter as you go along.
