Hi Sledgehammer carver water heaters are very reliable can run on lpg or electicity separately or both together' useing both hots up the water quicker(if you are going to use gas(most people use the red bottle calor gas this can be used all year round) the blue bottled calor gas can not be used in very cold weather as it will freeze, calor supply a uk network readily available at most garages, garden centres etc. you can have a gas tank fitted(gasflow) then you have to find a garage who sell the gas when you want a topup.
reference the water freezing most motorhomes have a inboard fresh water tank under one of the locker boxes, the waste tank sits under the chassis with a drain off tap on the side. If you intend useing the m/h in the winter in very cold weather you would not want to wild camp? there are plenty of good sites open all year round, most sites charge an all inclusive price 2 adults mains hookup free showers etc, we make full use of the electicity we use a small ceramic heater with saefty cutout, hope you will find tis of some use to you good luck with your motorhoming days Tony
