The difference it made to me was incredible when I took out my wyvale and put this tank in the same frame in its place,the van felt so unsafe before and at traffic lights you'd pull up and rock till they changed to green. The grippatanks still leak aswell I've seen a couple of them in vans and the kids still leak,they look veryuch just like a big standard wyvale only in black which takes the emphasis off of the quality of them. My tank water in let is just big enough for transfer nossle and is completely leak free
Which tank did you put in?
I hav e a secondhand grippa 650 crash tested tank and frame that i purchased form alex gardiner , this is the tank they used to develop the grip crash tested tanks.
It is batter with gouges in the bottom that have gone half way into the plastic and it does not leak .
The lid is a decent size and has never leaked , it use a similar design closer to a submarine hatch .
mine didn't have the honeycomb baffles but they retrofitted them to the tank through the hatch and it acts like a solid load .
So in what way is it just a wyedale tank but black ?
its a completely different design and is unique .
