we are going away in a week or two and have just discovered my caravan spare wheel is missing the storage place is secure ,and they are not admitting it happened there, as i never checked it when i took it back its off a sterling eccles explorer twin axle van its size is 155 x 13'' for an alko chassis ,caravan supplies round here are no help where do you think i can find one? looked at some sort of rubber spray type thing that seals and inflates tyre wondering if this would be any good on a caravan? thanks for your help will scarborough
