If you are looking for a lorry with living accommodation , then be honest with yourself about what is essential and what is nice to have. If you are planning to attend numerous stay away shows a year, then you may want living that includes a cooker, fridge, bathroom etc, as well as room to sleep, but remember that this all adds to the unladen weight of the lorry, which then reduces the amount of payload you have for your horses, kit and other essentials.
Remember to check whether the lorry is setup with hook up if you’re planning to attend stay away shows regularly. For lorries with gas, find out where the gas bottle is located and when the system was last checked by a qualified Gas Safe professional. If your lorry has gas, it is sensible to have a carbon monoxide alarm fitted.
