The 7.0m long Browning trailer shown below opens out on both sides to give 50 sq.metres of covered space. It is mounted on a close coupled low deck 3.5 tonne cross chassis.
This Marwell trailer has a removable drawbar so that it takes up less space at exhibitions and shows. It also has a headboard, when the main flap is lifted up the green leafy portion will also be hinged up so that it is very distinguishable from a distance.
The dual purpose trailer shown below opens up on both sides and can be used for auctions (with sliding windows and a small counter) or as a hospitality trailer.

An alternative to barn doors are patio style doors, which have the advantage of being partially or fully open and are probably preferable in cold weather, as seen below.

An alternative to a lift up flap is a pull out awning as shown below. This trailer still has barn doors which protect the patio doors when being towed and open out to form display panels.
