Hi Peter
I chose not to charge the 'van batteries from the alternator simply because
1 The cruiser is already charging 2 under the bonnet (original and 2nd)
2 Two deep cycle in the rear which I set up from our camping days
I felt that was enough to ask of the alternator and so on our 'van I now have 3 x 130 panels and 3 x 105 deep cycle and the 'cruiser batteries in the rear are really sitting there doing nothing when we will now start using the 'van
the 'van system is working a treat and perfectly in balance and I doubt I will ever need to use the spare power available from the 'cruiser.
My post was more along the lines of "what if" I am down on available amps in the 'van one day for whatever reason 9extended non charging situation etc) and how was the simplest and easy way to parallel the 'van to the cruiser to tap inot the 'cruiser back batteries
The 'van has a spare solar input via an anderson on the side and I wondered what would happen if I plugged the 'cruiser spares into this ....simple and no prior preperation needed
It seems that perhaps voltage drop through the PL60 may be an issue and I guess from all the answers to my post that I should perhaps
1 Wire in a dedicated lead to be able to parallel the 'van battereis when needed (if ever)
2 Use the DC DC charger to boost this charge from the full 'cruiser battereis to top up / allow draw on the 'van batteries
thanks
Graeme
