On ferry crossings i would eat a meal before getting on the vessel then sleep in the cab.
The negative points are a fire on board or if the vessel sinks or an ADR load leaks acid or gas.
The crew would have no idea is in his cab.But you get a good sleep.
P&O Hull - Europort, P&O Hull - Zeebrugge, Stena Harwich - Hoek, Stena Killingholme - Hoek are all good boats. You usually have a cabin to yourself , the food is decent enough and free and if you like, there is a bar and freight drivers lounge (except P&O Zeeby).
Negative points, you occasionally have to share a cabin or have a cabin with a shared toilet/shower. No worries about ‘what if’.
