A cheapo, run down looking shed is less likely to attract the wrong kind of attention, if it looks like it's a dump it's less likely to contain valuables. We have never had a break in, a few neighbours have over the years had valuables walk, locks busted in. I geuss virtually always having someone home and a run down looking place it is kinda obvious the stuff we have is also going to be well used, go 2 doors down the road, immaculate lawn and driveway etc, new car on the drive it's a no brainer the lawnmower and strimmer were going to be near new condition, well serviced and easy to sell at a decent price. Our cars are all over a decade old, the lawnmower is even older. It doesn't help if you need a smart van for work and dependable tools, it's kinda a necessity. I'd be looking at trackers that alert your phone it the vehicle moves, fit 2, 1 more east to identify than the other.
