Adding a leisure battery

Hiya all.i have a victron leisure battery set up on my day van.i would like to have a second battery and solar panels on roof.ii am near Dartford in kent.ia there anyone near who would install thiese?please

I do not know if this will help. You may be better trying van / caravan forums as they may have links into fitters who specialise in those markets which are different to domestic.
