In general, we've had our CUB for a few years now, used it thoroughly, despite it not being an of road version, much of our trips have been off road and despite being fitted with CUB's stone guard, I'd have to say most damage has been light and from stones thrown up by the 4BY, damage to plastic piping, wiring(despite being enclosed in tubing)the gas tap to the bayonet fitting was also damaged by stones, nearly fell off, it had come loose from the hammering it received, could probably benfit from better locating to avoid same.
It's come thru with flying colours.
Most of our gripes are minor ones which I would think the factory would pick up and take on thus making their product even better.
I've instaled 12 volt system, together with pressure pump for the sink,(the tap was hard to source but they can be had here, OZVAN Caravan RV and Camper Assessories Online, part no Cah3546-605/005990 single folding tap priced @ $86.24) didn't want the plastic one,power outlets outside for lighting in the annex area and power intake for Solar Panel, the whole runs on a deep cycle battery of 130 AHrs. The water tank had a proper shepards crook over flow fitted, thus the tank fills up fully every time.
I do get tired though, adjusting the brakes,(mechanical, cable activated) can't believe how often this is neccessary.
The tyres that came with the camper, were a disaster causing blowout on a trip, the tyre people wanted to know who fitted them, as the were ILLEGAL, fitted 3 light truck tyres 8 ply, no problems since. I've also had to fit bottoming stoppers, as the larger diameter of the tyres would occasionly cause them to hit the top underside of the mudguards, these stoppers are a solid rubber fitted onto the top of the spring attachment fittings, now instead of the tyre bottoming out, the stoppers do the job.
