That's exactly what I did starting about a month ago - I've got enough on hand to last about a month (most of that is committed to catering jobs that already have a set price - so my forecasting is much easier but if I didn't lock in the price I would have to eat the difference).

As long as they are safely handled I've found no quality difference at all when freezing stuff that is cryo-vaced. More often than not it has already been frozen at least once before it gets to me.

I don't ever sell anything that has been re-heated after cooking though. You can also do that with little to no quality loss but I try to position myself as a premium brand so everything is 'cooked to order'. There are also a lot more food safety concerns (cooing it fast enough, re-heating it fast enough, etc.) that I don't want to worry about. I vacuum seal cooked BBQ at home and it's just as good as fresh but you can't do that in a commercial setting without special permits that aren't available to food trucks (at least not in my area).
