All Eriba Touring range vans get a hob, fridge and space heating as standard.
The standard hob has two burners and there is an option for a third burner, but using three pans on the hob is well nigh impossible.
The fridge is a 3 way absorption type, except on the 535 when a 12V compressor type is standard
The space heating is gas fired as standard but a 240V electric element is an option.
A boiler is not standard except on the 535
The option of a mains electric 5 litre boiler is a bargain whilst the gas and mains electric 10 ltre boiler is a very expensive alternative that is really only worth paying for if you always pitch without 240V available.
