Hi Andy, I did some work on car/ caravan power boosters some time ago.
There does not seem to be a ban on then, but from what I've read they are discouraged as the EMC from any switching devices can cause havoc with the many electronic systems in the car. Some models are a lot worse than others.
With a homebrew design it could be difficult to test correctly and you may have invalid insurance if your electronics causes an accident (or the overpaid lawyer decides it is remotely possible and convinces a judge of the same).
I would be interested in hearing others views.
From the caravan point of view, unless a different connector from the now standard 13 pin one is fitted, the max current is 10A per pin. On the earlier 12 S/N (7 pin type, some of the connectors (but not all) could be run up to 15A.
