Thanks Lee for your hard work.
When it comes to crash testing, I'm only concerned about HyGe sled tests. Crash tests use the vehicles crumple zone. That's all great, but I know 100% that when a system survives a HyGe test it will be okay when the vehicle is crashed. Not sure you can be 100% certain about it the other way around.
Only system I would want in my new van is the Grippamax system, because A: it's been designed by Alex and B: it's done the HyGe sled test (with 1000 litre tank I should add). Its also easy to fit and can be completely customised with the cover plates.
