Some recent modifications I've done to my Utility Trialmaster with help from Expedition Centre in Sydney AUS. I'm converting my Grenny to be my full-time adventure camper. I can add pictures later if anyone is interested, let me know?
- Replaced the stock steel battery box with a custom light-weight aluminium version (20 kg lighter)
- Instead of one lid, this box has two lids that pivot from the outside towards the middle (rather than one lid opening rear to front). This allows me to access either side of the box to service the stock or aux power systems independently. This in turn allows me to be more flexible with storage on top of the box.
- Maintained the stock electronic setup on the left, minus one of the stock batteries (saved 28 kg)
- Added on the right side: 280ah lithium auxiliary battery, the new redarc alpha charger, 2000w inverter for 240 volts, plus all the wiring, fuses etc
- The redarc alpha charger has a feature that enables me to feed the starter battery with the auxiliary battery in case it has lost all charge, hence I could remove one of the stock batteries to save space and weight.
- Rewired all roof power points to the Aux battery so I can run camping lights without impacting the starter battery charge.
- Installed 430 watts flexible solar on the roof (glued) to feed the 280ah lithium
- Installed a 60L stainless steel water tank, inside a storage cabinet, in the rear cargo space. This includes a water tap and quick-fit water outlet (for shower hose) at the rear door, powered by a water pump.
- Storage/water cabinet has a fold down table, next to the water outlets, where I have a single burner induction cooker.
- Simarine display to monitor water and battery levels.
- ARB twin air compressor under driver seat.
- 270 degree freestanding awning.
This has been an investment but it all works fantastically and I couldn't be happier with the results. There are a few things I'll be adding to this in the (near) future in terms of internal storage solutions, but I'm building as I go to keep it as simple and minimal as possible. I go on regular trips to trial and test before installing anything new.
edit: added a picture from last weekend
