how can create two data table to save one form data in laravel

I am going to develop Auto Classified advertisement system using laravel. in My application there are six different vehicle types as,

car/van
Motor Bike
Lorry/bus
SUV
Boat
heavy Machinery

when some user is going to post an ad under one of above category there are some common columns name and some different columns values in the form, as an example consider car/van category. in this form have following form filling values

states
town
brand
series
transmission_type
millage
color
fuel_type

and consider some ad under heavy machinery category, form

states
town
brand
engine_size
bucket_size

you can consider there are some common columns name like states,town,brand and some different columns name values. so, I am planning to save same columns name values as ads_info table and other different columns values to vehicle_info table in the same form. but My problem is how can I create vehicle_info table architecture. i have no an idea about this. can you give me some solutions?
