BUR #25689 is pending approval.
create alias rv -> recreational_vehicle
create alias rv_(vehicle) -> recreational_vehicle
create implication camper_trailer -> recreational_vehicle
create implication camper_trailer -> trailer
I believe the current tag should be aliased because the tag is really short, so a longer tag is needed for visibility. I'm also proposing a BUR for the camper trailer to be implicated to both recreational vehicle and trailer.
