30mm clearance.....I'm thinking it looking better

I have Mulgo side steps....I believe Daniel will also be at film festival this weekend, would you mind having a look at his side steps to see if the plates will interfere with the tank....there is some adjustment and mine can go out further.

Cheers, Murray

Just noticed that level gauge/switch is on the size of a 10c piece.

Those side steps look to be mounted similar to mine so shouldn't be a problem. If Daniel is at the film festival I'll say g'day and check his out

A sort of bash plate below them... whilst the tanks will be pretty darn solid dragging a rock could easily hook and tear out a strap..

Yeah have thought of that, would be easy enough to make a bash plate if people are worried. I'll be testing mine without and reckon it will be fine as they are very well tucked up, will see.

Got it all plumbed and wired up and filled it up! Happy to say that I used a high flow pump full bore no worries at all, got about 70L before it clicked off then finished filling a bit slower but all up a very quick fill. I got 86 litres in which is still pretty good. The three breathers are just off the top of the tank so there must be about a 10 litre air gap for expansion.
