Zip zero zilch. The RCWs nor the WAC state anything about the vehicle must have doors. What it does state is IF(key word here) vehicle is equipped with doors, they must be equipped with a locking mechanism. Obviously it is a safety issue if doors on a vehicle cannot stay shit.
Many vehicles are manufactured without doors or sliding doors or even completely bodiless as in the case of farm equipment/construction vehicles which can still legally travel down a highway as long as it is sporting a big triangle on the ass end.
As with anything, cops are clueless about half the laws they enforce.
FYI, my rig rarely has its doors or top on during the months it does not rain here. Never been pulled over for it in 4 years.
