This is all very dramatic
from the past when this subject rages on - my understanding is a strapped down tank does NOT class as a modification - as long as it doesn't overload the vans payload - it is just cargo - no different to 20 barrels of chemical in 25 litre drums etc.. or a cement mixer or a large pallet of books etc..
Bolted in IS a mod - the other thing to consider is self employed Vs employing - as self employed you can do things that a company that employs should not or can not do

That was the same argument I used with several insurance companies and failed to get them to see the logic.
Bolted in was a mod - sitting there was an unsecured load.
I asked how this differed from a cement mixer or wheelbarrow and was met with silence and then told it's not the same thing because you can take them out.
I replied that I could take the tank out but was again told it wasn't the same thing.
Most read from a script and lack the power of rational thought, or probably any thought. As far as they're concerned, rules are rules and we're not paying out.
You just keep going until you find a company that's capable of going off script and actually listening to what you're asking.
