No way, park on airport road
There are two parking lots - the lot further East, Directly off Valmont, might be your best bet. Weekday mornings might be fine but it does get crowded evenings and weekends. There are industrial parks nearby where you may be able to park the trailer for a few hours and bike or walk to the bike park.
Gets crowded. I'd be surprised if you could fit such a big trailer in the lot.
