They certainly have lived a Spartan life...this is from their account of life in their first van.
‘To give some examples, during the past week or so that we've been enjoying the peace and quiet of this beautiful Spanish beach camping we've been pretty mindful not only of minimising use of our water pump to save power, but also minimising use of gas.
The reason for this is that we don't have a refillable system, don't have space to fit standard Spanish gas bottles in Homer's gas cupboard and don't fancy spending a small fortune on the smaller CampinGaz ones either. Instead we're hauling 2 extra French 5kg bottles with us, one of which is living in the habitation and we have to move around it throughout the day. However, since this has to power our fridge we're in full gas conserving mode, not only cooking some of our meals on a meths burner outside (which gets enough funny looks) but also showering in the frosty, but free, beach showers close to our parking. In fact, use of any warm water whatsoever in Homer is strictly off limits for the foreseeable future! And don't even think about the heating either if it gets chilly, we've got extra coats for that.
Coming back to the water pump, after our scare with the leisure battery and top up by our kindly neighbours, we're also now acting the role of 'tap' for each other by pouring water from a plastic bottle over each others hands or any crockery that needs a rinse when it comes to washing up.
