Here is a tip I use to give more flexibility in the Cali, it needs a mod which costs nothing and takes about five minutes to do.
The picture below shows the rear seat slid right forward, giving access to the rear. This is handy to use the loo when travelling, just slide it forward from under the rear shelf, drop the blinds, and thro a blanket over the headrests.
It’s also useful to carry furniture etc around! Also gives easy access to the tool kit when the boot is full of stuff.

To enable the seat to be slid this far forward the stop (below) has to be removed. This is located in the rail nearest the kitchen, about 30 cms from the front. Slide a screwdriver along to locate it, then unscrew it.

To remove the stop after it has been unscrewed, you have to remove the plastic trim at the front of the rail, then slide the stop forward. The plastic trim can be removed by levering carefully up at the front.

Keep the stop somewhere safe in case it’s needed, pop the trim back rear end first and tap down at the front. That’s it, now you can use the loo
