The previous owner had a Strikeback alarm fitted and that has a jack on the back of the Hymer which takes a security cable which you thread through the bike and plug in to the socket and in theory, you know when the alarm goes off that someone has stolen it!!
I have seen the Chinese scooters on the www and some sites are selling them for £550 and above. I am not interested in styling, just "does it do what it says on the tin" The scooter (and generator) are probably in the category of Big Boys Toys and I suspect that I might eventually decide that they were not that necessary in the first place, but I bought the van with a fitted motorcycle rack and the alarm thingy so it is just the cost of a scooter. If I can buy a cheap(ish) second hand one and the reality matches the expectations, then I could eventually buy a new one.
A good old fashioned Vespa would be good, but they seem to be going up in value like the older VW camper vans!!
