Hi, I’m in Bristol and I too am done with Heritage. Originally they told us we had 1 leisure battery on our brand new California, they replaced that battery saying it was faulty, still had issues over the year charged for diagnostics only to discover ourselves it had 2 leisure batteries … Heritage would not acknowledge their mistake despite all their invoices. Lots of other issues subsequently with them. I persevered with them for a few more years, but no improvement - just seemed to lack knowledge. Trouble is, I desperately need a reputable person to now look at the electrics for my leisure batteries, fridge and do a gas service. Did you find any good garage who understands the campervan workings of a Cali? i desperately need to find someone otherwise I’ll have no fridge for my campervan trip. Thanks for any suggestions!
