We are currently doing the same to our 90.
Have put 3 aluminium drawers in the back with a 55L water tank to one side and the 50L fridge to the other side(drivers).
Dual battery is an ex Telstra standby 100AH unit that sits between the tubular strengthener behind the seats and the fridge, with the Redarc isolator in with the original battery.
ARB compressor under the drivers seat, ARB bulbar and Warn Magnum 10k winch up front, with IPF LED spots.
We also picked up a cheap 2nd hand roof rack, that we have tidied up and put mesh on, this is mainly for if we take the Oztent, but we generally take the Tvan.
Just about to receive 2 gullwing doors for the rear windows, which will make accessing the fridge and storage much easier.
We will be doing 3 weeks on the York peninsula over xmas and then 6 weeks in the Kimberlie middle of next year, so will give it a good test.
In time, we would like to complete the package with at least 1 sill fuel tank (probably a Brown Davis 55L unit to the drivers side) and a change of springs to bring the ride height back up to standard (thinking of 90 rears in the front and either airbags or 90 HD in the rear.
Cheers Cookie
