A very useful accessory to check your motorhome spare wheel that is tucked away under the van. The worse thing to happen if you get a flat is to find your spare is flat too!
I fitted one to our last van (our current van came with one fitted) – and we got a flat tyre on the French motorways – fortunately spotted when we stopped for fuel.
