Totally agree with Alan, the cost of membership (£12.50 AFAIK
) makes joining a realistic investment.
The backlog of the problems tackled is immense and for a member, is searchable. That material stays available whereas Motorhome Groups on Facebook cannot be searched for specific content, although the instantaneous nature of nominally having 60,000 members on FB would seem excellent. But that is a fallacy and you cannot hi back to a doe ific person for elucidation.
I know nothing about your specific vehicle, but it is easier and quieter to use solar panels than a generator. For a useful generator you probably also need a supply of petrol, small, low powered ones are petrol and I have never come across a diesel. That means carrying potentially, very flammable petrol in a container...... It is possible to convert some petrol generators to run on LPG, but that is not an easy task and foes require technical know-how. Generators are also VERY unpopular on aires etc (actually illegal) as the noise is very intrusive. Solar panels are silent and cheaper to buy/install/operate.
A large battery capacity is highly desirable and not difficult although careful siting and connections are essential, once again, detailed planning and know-how are required.
So, although I can give dome GENERAL advice, much more research and information is required. Do keep us updated with what you decide and carry out.
