I wouldn’t wait until May 1 to at least contact your dealer and find out what information Lund gives them about the build and delivery dates. However…
Be prepared to be told “they don’t tell us anything” until it’s built and/or shipped. Which, of course, would beg the question where did you get the May 1 date from…
Not that there’s anything you can do about it except wait anyway. I mean, nobody’s going to risk giving up their place in line when for all they know their boat could get built tomorrow.
I waited 2 years for a SXS/UTV and this seems to be just the way it is with rec toys right now. Customer satisfaction? Who cares! The dealer attitude is you’re lucky to get one at all.
