Caravan Weights

By |December 19th, 2014|INTRODUCTION|0 Comments

Thinking about buying or building a caravan has a lot to do with the towing capacity of the vehicle and the towing safety. Towing a van just below the towing capacity of the vehicle is not necessarily a save option.

Towing capacities are calculated by the vehicle manufacturer on the basis of axle loads and drive train characteristics. A maximum towing capacity does not mean it is independent from the length of a trailer. A short heavy trailer might be safe but the same weight stretched over 28′ is most likely not.

Caravans are inherently unstable and the longer the worse […]

This is the story of the design and build of the Inno-VAN-tion concept van. It is meant to be a research platform for various technological advances in testing the safety and tow ability of a trailer. We will introduce and describe these concepts at a later stage, once the van is finished and the first prototypes of the new tools have been tested.

During the design stage of the van I have been asked to document the process and the results, however the design process went through many iterations and it would be far too laborious and also boring to […]

Points we do not like with US and local 5th wheelers and goose neck trailers

By |December 17th, 2014|WHAT WE DID NOT WANT|0 Comments

In no particular order:

King pin coupling is inefficient (too heavy, big, and not sufficient articulation)
Goose neck auto lock coupling is expensive and inconvenient to use
Most local goose necks are built for flat trays not tubs
Wheels on US 5th wheelers are too far forward
Not enough clearance between vehicle and van to hang motorbike
Bed room over neck makes van far too high
Generally CG (Centre of Gravity) is too high
Chassis mostly not suitable for gravel or dirt road
Too much space wasted with seating which is not required for 2 people
No real office area
Designs are old fashioned and dull
Cheaply made interiors and appliances […]
