Yeah it doesn't have so much grease nipples as an average Landcruiser.
Will you do sand driving? Then at least buy a decent air compressor for your tires, so you can air down the tires without worrying about it. If you air them down to 14psi you will get through a lot of sand. In fact, I once passed a F150 truck with nice big tires at high pressure, which had difficulty to get through. While I was able to pass without issue in the soft sand.
Well the van is pretty simple. Some emergency things to think of:
- Figure out how the engine is stopped. If you can reverse that manually, by pressing a lever or something by hand, you don't need ANY eletrical system to work but still drive the van (when towed to start) (this is also on my todo list to check how it is done)
- Regularly check your air filter. Practice it once.
- Bring a spare fuel filter and oil filter and likely engine oil
- Bring a spare fan belt (although you should already have two)
- If you have 4x4 by button (parttime 4wd): When the rear propshaft (to the rear axle) fails, remove it completely. Enable 4x4 and you now have front wheel drive.
- Locate the thermostat. If the van keeps running hot and the coolant level is okay, try to run it without the thermostat to see if it helps. (of course replace it later when your back in Canada with lower temps, but in desert you don't need it)
Flush the coolant system before you go perhaps?
Anyway, those were some suggestions. However, I don't know about which grease to use
