Our Trakmaster Gibson
Apart from the normal servicing we've done on it the only repairs have been to a stub axle we cracked on the Old Andado-Mt Dare track when we hit a severe bulldust patch while an awning had to be replaced and the roof repaired after I tore the awning off on a track on the Dampier Peninsula. Oh yeah, one other thing, the 240V power inlet socket sits proud on the side of the van (as does the 240V outlet on the other side of the van) and a wayward branch wiped this out on an early trip.
Its trailing arm suspension is backed up by 285/75R16 Cooper STT tyres fitted to 8-inch rims with feature more offset than normal to give the tyres clearance in the wheel well.
The suspension has worked extremely well whether we are cruising on the blacktop at 100kph, along a heavily corrugated road at 80kph or crawling along a rocky highly eroded track at 10kph. Apart from the afore mentioned stub axle crack and signs of where a few rocks have pounded the shocks and under carriage the whole suspension continues to work just fine.
Backing up the dual battery system is a Projecta 80-watt polycrystalline solar panel all controlled by a Redarc Battery Manager 30 control unit, which does a great job
