Any vehicle in an emergency is better than nothing at all, but if you want the most practicle & advantages of vehicles, then you need to get a good 4WD (four wheel drive). I had three 4WDs when I lived in the Territory, we lived off grid, & it was the only way to get around. We had two Toyota Land Cruisers, a short wheel base & a ute, & we had a little Suzuki. I would still have the SWB, but it was stolen from our property whilst we were away looking for land interstate.
Now we live in New England NSW, & up until now we have had a Nissan X-Trail SUV. However, the wading depth (depth of water it can drive through) on this vehicle is only 400mm. Of late it has been very wet here, I would say the wettest we have experienced in the past 30 years. Weather conditions are changing!!! We have a creek to cross to get into town, as again we are living off grid in a forest. The alternate rout out & back in if the creek is in flood is all dirt & it too is subject to a lot of water.
So, we decided to get a full blown 4WD, we do already have a 4WD unregistered property vehicle (Lada), but it can not be used on the road. We sold our SUV to my Eldest son & his family for an affordable price. It is better than the ordinary sedan that they had. What we purchased is a Toyota Hilux twin cab diesel ute with a canopy on the back & a bull bar. We also added a rear view camera, & we are getting LED bar lights fitted to front & rear. So far my wife is very pleased with this vehicle, though it is larger than she has been used to driving. I love it, it gives me a feeling of security knowing that my wife can get home at night no matter which rout she has to take.
The wade depth on this Hilux is 700mm with standard suspension.
This is my youngest son's Nissan Triton which I believe has a wading depth of 500mm. This vehicle is a good less expensive choice in 4WDs.
My Russian Lada 4WD with wide wheels & two spares on the roof.
We do not expect to ever have to evacuate our forest home, we have enough people to be able to defend it in a shtf situation short of a foreign invasion. But if we should have to leave, I feel sure the vehicles we have will get us to where we are going.
