I really think the dealers do not know at the time you order. The dealers do not seem to have an inside track as to when a specific model will be built and the factories tend to do these things in bunches so 6-8 weeks seems to be a common estimate. Although some who are more honest will stress 10 weeks plus if an order is placed during the busiest time of the year and to allow for inevitable delays.
My own experience: I ordered a Shamrock 233s on March 15th from a local dealer and was given the typical 6-8 weeks for pickup. The trailer was offline on May 17th and I was scheduled to pick up on May 25, but the driver shortage last spring caused a delay and the camper was delivered to the dealer on the Thursday before Memorial Day. Since the techs at my dealership had off on Friday and Monday, they didnít get to work on it until the Tuesday after Memorial Day - 11 weeks after the order date.
