Buy or hire the MP6812 if...
- you want one that is 1,227kg lighter empty
A step up from the MP6810 for buyers wanting slightly more load capacity for camping, leisure or light commercial use. The extra 15cm of length and 37kg of payload over the MP6810 is the difference between a boot-load and a small van-load, at a weight any car can still tow.
