A. What do you need? Built in or portable? Front or top loader? Will you be running it from mains power, generator or use an inverter from on board 12 volt batteries? Will you be on a water source such as at a caravan park, or will you be collecting water from a stream? Do you need a washing machine?
Will portable that can be used outside be easier for you than one in the bathroom or under your bed? A portable will be easier of you are bucketing water from a stream of lake to supplement you tank water supply. Portable machines can be purchased for around $100 to $150, considerably less than built in machines.
If choosing a portable machine, which is better, twin tub or single? A twin tub may be more convenient if you want to use spin cycle only. The spin capacities of most portable twin tubs are less than the capacity for the wash bowl.
If inbuilt, do you want a top loader or front loader? A front loader is likely to be heavier and not result in a saving on water usage. You will also need somewhere to mount it where the door can be easily opened and allow room for you to remove the clothes when washed.
Most of the following will run from a generator or small (eg 300 watt pure sine wave) inverter with adequate battery power.
While there are others, the main brands which can be built in can be seen at Caravans Plus and this will give you a guide to the current prices for these brands.
