I don’t know if there is a best time of the year… it would depend on the individual… end of year means settling for what you can find, and if you can find… then the dealer has his cost and the years’ worth of floor plan to recover… I never saw much value in show pricing unless there was a significant manufactures incentive thrown in…
If there is a best time I think it is ordering new just as the model year is changing… when you get next year’s model at this year’s pricing… your trailer is always a year newer for trade or sell purposes… I bought my 2000 in 1999 and my 2004 in 2003… I don’t think I paid any premium for doing so…
