What's a camp cupboard?

Yes - take a look at the Camping Bug site for a good range of water tanks. It really depends what you exact needs are; do you camp for a long time? are you a large group? do you camp in remote areas?
you can probably send them a question and they will advise you.

Which country are you in?
What model of extractor is it?

If it's in the UK, the chances are it's either run off the lighting circuit or there's a mains connector in a cupboard nearby (look for a hole in the back panel), or even at skirting board level, so you have to remove the kick plate & look under the cupboards.

BTW, it's unlikely to have an internal fuse although the motor may have a thermal link for overheating protection.

The recommended stove for ultra-light backpacking, if you don't want to carry much weight, is the alternative-fuel stove.

I advise you to choose a small folded chair that doesn't take lots of room in your backpack while he's folded. In addition you should choose a chair that he's light-weighted so it won't be a burden while you carry it.

If you're going to a RV trip right to a campsite you can choose between two types of camping chairs, the basic camping chair and the comfortable camping chair.

I'll advise you to get the lightweight camping chair; it's easily folded into every backpack and it's very lightweight which will make you carry much less weight during your hike.

Make sure the mechanic did replace the thermostat, and have somebody check the fan clutch. An exhaust restriction could also cause it to run hot under a load.
There is a small chance the water pump impeller is shot inside the water pump and not pushing the coolant thru the system.

The magnet needs to be less than about 1/4" from the light when the door is closed to activate the magnetic switch in the light and turn the light off. Fix the light to the frame or wall inside the cupboard and the magnet to the door.
