For your motorhome, if you have an awning, you need an awning skirt! Here’s why ; Awning skirts – Why do you need them ?
For motorhomes, make sure that you have a hose & tap connections & carry a jerry can or suitable water container, as it’s not always possible to get to a tap.
Wether for the heat or the cold – get & use Internal Thermal Blinds! Read why here ; Thermal Blinds
To change a tyre make sure that the wheel jack can actually lift the motorhome. The supplied Fiat Ducato jack CANNOT lift up my Burstner 747 2Active !
I always carry 2 x 20 ltr full water cans and wow they come in handy.
Always have a CO detector fitted & test it regularly.
If you have an awning, make sure you have a tie down strap. In windy conditions it is an absolute must.
