We have a Challenge Meridian and love it... 12 ft tent = lots of space for our gear and the Jack Russell! We don't use the annex unless somewhere for a number of days and have, during quick overnight stops, just taken to rigging a tarp over the kitchen area if it looks like a bit of rain around. This trailer has been across the Gibb River Road, up to Cape leveque, down the Tanami Road, numerous trips to Kings Canyon/Alice Springs area, from Byron Bay to Steep Point through the heart of Aus, back across the Nullabor, up the East coast and most recently over to the Flinders Ranges. Not to mention all the quick weekends away around Vic. The camper has come through it all magnificently.
The staff at Challenge Campers have been fantastic whenever we have had a query or question about the camper and we can't recommend then or their product highly enough.
I think we will be keeping ours until too old to climb onto the bed!
