Buy or hire the Cadix if...
- you want one that is 2,332kg lighter empty
A mid-sized camping trailer for families wanting more load space than the Alicante for tents and holiday gear. The 205cm bed is the practical difference: it takes a folded awning or a family tent lengthways, which the shorter Alicante will not. Still unbraked, so no servicing beyond lights and bearings.
