Please bear with me; this gets head achingly complicated.
There are rules about what you can legally tow in the UK.
The basic rules (assuming you have a valid licence) are that you can't
load the towing vehicle over the GVW (Gross Vehicle Weight), you can't
load the towed vehicle over the MAM (Maximum Authorised Mass) and the
combination of towing and towed vehicle cannot exceed the MTW (Maximum
Train Weight) for the towing vehicle. The TC (Towing Capacity) must be
equal to or above the MAM of the trailer.
All reasonably straight forward so far, the weights listed above are all
in the vehicle/trailer documentation. There is some question over having a
combination where the GVW + MAM are above the MTW but the vehicles are
loaded below the MTW.
There is, of course, an added complication. If towing a caravan the body
length (excluding A frame) should be 7 metres or less for any towing
vehicle up to 3,500 kg GVW.
This is a speciality of the UK, though. In Europe in general (as far as I
can establish) towing caravans over 7m in body length is fine. This
explains why Hobby, Tabert and Fendt (for example) manufacture caravans
with a body length over 7 metres.
As far as I know it is (arguably) legal to tow with a combination which is
legal in your home country. So, for example, a German caravanner could
visit the UK and legally tow a combination which is illegal for a UK
national in the UK.
Getting towards the end now; we went and had a look at some German
caravans. Unsurprisingly the main market for these large caravans is the
traveller community and the dealer was obviously closely tied to
Travellers.
We asked about the "over 7m" problem and were assured that the dealer was
regularly stopped and questioned by the Police (we suspect because they
were Travellers, not because of the size of the outfit) and has never had
a problem with body length over 7 metres.
The combination of a Nissan Navarra (GVW 3,500 kg, MTW 6,000 kg, TC 3,500
kg) can comfortable handle a caravan with a MAM of around 2,200 kg.
However a vehicle of GVW of 3,500 kg cannot legally tow a caravan with a
body length of over 7 metres.
https://www.gov.uk/towing-with-car/car-towing-weight-and-width-limits says:
"The maximum trailer width for any towing vehicle is 2.55 metres.
The maximum length for a trailer towed by a vehicle weighing up to 3,500kg
is 7 metres. This length does not include the A-frame."
Possible room for interpretation, but I would assume that this means up to
and including 3,500 kg.
We are assured that these potentially illegal combinations are stopped
regularly by the Police, but then allowed to go on. Accepting that this is
a dealer talking, I am inclined to believe him because otherwise he would
be running commercial vehicles over 3,500 kg GVW as towing vehicles.
Accepting again that the vehicles on the site might just be coincidental.
However that way lies conspiracy theory.
Given all the above, it it likely that the Police are not enforcing the 7
metre rule?
The Internet is not much help; I can't find any links to people being
prosecuted. I can find lots of discussion. I can also find people
admitting they tow potentially illegal combinations without ever being
stopped.
One person claimed to hire a mini bus (which has a GVW of over 3,500 kg)
to move the caravan between summer and winter quarters.
Does anyone have any knowledge in this area?
The ticklish bit presumably would be informing insurance companies that
you were towing a caravan over 7 metre body length with a vehicle with
3,500 kg GVW.
As I said, head achingly complicated.

P.S. the intention is to tow the caravan on the continent for long breaks
near the Med plus some touring in the UK.
TL;DR can I break the law and get away with it if the Police are tacitly
ignoring it?
